Chip Revision Errata Information:
following errata items apply Revision 56F803 devices. These parts either marked DSP56F803 PC56F803 with date codes 0137 greater (bottom line marking).
Errata Number Description Quad Timer, when Pulse Output Mode, clock rate yields pluses. outputs disabled during DEBUG mode. Impact Work Around Impact: clock rate creates extra pulse. Work Around: Program pulses only when operating Maximum clock rate. Impact: Safety considerations outputs disabled prior entering DEBUG mode. Work Around: Disable outputs prior entering DEBUG mode. module will continue operate while DEBUG mode unless explicitly disabled. Program Flash Interface Unit (PFIU) address register read returns wrong value when writing out-of-row address. Analog input voltages measured properly. Impact: When verifying out-of-row write, PFIU returns address applied Flash pins, which concatenation register ADDRESS[4:0] bits. Work Around: None. Impact: Inputs 24mV yield measurements Work Around: Bias Analog inputs above Optimal Setup Impact: Better Accuracy Work Around: Recommended values ADCDIV Register:

Errata Number Description register available cycle immediately after value change. Impact Work Around Impact: case index+ offset move into register, available cycle immediately following change value. Example: move (R2) Work Around: no-operation (NOP) will need inserted between statements. assembler will modified flag this problem. Timer GPIO interrupts cleared when clearing other interrupts. Impact: timer GPIO modules have several interrupts cleared writing same register. Unfortunately, clearing interrupt unintentionally result clearing interrupt that occurred between time status register read written back. Work Around: enable multiple interrupts single register. Slave Mode (transmitter empty) flag early. Impact: problem only occurs Slave mode when CPHA Transmitter Empty (TE) flag early, thus allowing user software write data value into transmit buffer before current contents loaded into transmit shift register. Work Around: receiver full flag indication when write data into transmit buffer. Slave Mode transmit shift register data corruption. Impact: problem only occurs Slave mode when external master deselected internal (SS=1) provided shift clock internal SPI. This scenario expected system with multiple slave devices. deselected slave transmitter shift register will shift response applied shift clock. This action will cause existing data transmitter shift register become corrupted. Work Around: Modify communications protocol first word returned Slave after being reselected (SS=1 discarded. second subsequent data words after being reselected valid. 10.6 Stabilization Time Impact: Maximum stabilization time 200ms under worst case (-40C) conditions. Typical stabilization time remains 10ms (25C above). Work Around: Insert 200ms delay after power allow settle verify Loss Lock bits (LCK0 LCK1) Status Register (PLLSR) prior program execution.

Chip Revision Errata Information:
following errata items apply Revision 56F803 devices. These parts either marked DSP56F803 PC56F803 with date codes 0137 greater (bottom line marking).
Errata Number 11.8 Description Missed MSCAN transmitter empty interrupt Impact Work Around Impact: When disabling enabling MSCAN transmitter empty interrupt enable (TXEIE) bits transmitter control register (CANTCR) while transmitting peripheral will sometimes miss transmitter empty event. missed event means that ITCN peripheral will notified interrupt service routine transmitter empty interrupt will invoked. sequence below required problem: Start message transmitting TXEIE CANTCR enable MSCAN transmit interrupt. Before message transmission completes clear TXEIE CANTCR disable MSCAN transmit interrupt. very small time window around completion transmission TXEIE CANTCR enable MSCAN transmit interrupt. rare instances above sequence will cause MSCAN peripheral miss transmit empty interrupt. Work Around: most direct work around enable MSCAN transmitter empty interrupt CANTCR then disable enable interrupt using TXEIE bits during active transmissions. disable enable MSCAN transmit empty interrupts during active transmission ITCN peripheral interrupt vector bits. disable transmit interrupt PLR14 bits GPR2 register should zero. enable interrupt PLR14 bits priority above. Using ITCN perform interrupt enabling/disabling function corrects issues never misses transmit empty interrupts.

Errata Number 12.8 Description pipeline dependency problem occurs secondary data when read addresses second parallel read crosses address boundary. Instruction sequences which induce this problem combination following: Dual Move Dual Move coupled with MAC, MACR, ADD, SUB, MPYR. memory boundary that issue DSP56F803 0X3FF0X400. Impact Work Around Impact: This problem only applicable assembly coded algorithms will occur algorithms written entirely also applicable when code uses certain libraries primitives that written assembly when data structure local variable (i.e. allocated stack). Typically, second read dual parallel read coefficients filter. Calculating FIRs context primitives affected this condition, with exception (xfr16mult). libraries that affected this erratum V.22, Caller G.165 Function library (dfr16FIR, dfr16FIRs, dfr16FIRInt, dfr16FIRDec xfr16Mult). more details please Motorola FAQs http://www.motorola.com/ semiconductors under Technical Support Contacts. Example:
y0,x0,a y0,x0,a x:(r1)+,y0 x:(r1)+,y0 x:(r3)+,x0 x:(r3)+,x0
yields different final result than,
y0,x0,a y0,x0,a x:(r1)+,y0 x:(r1)+,y0 x:(r3)+,x0 x:(r3)+,x0
when initial value 0X3FF (1023). same problem occurs when decremented move from above boundary below. This problem only occurs sequential read accesses which secondary data which cross word boundary internal data RAM. problem results from incorrect logic used mediate between multiple internal 1Kx16 memory blocks. Work Around: Work arounds code written user order preference): Move constant coefficient tables from data data FLASH. (Define coefficients const appconst.c, then linker command file will automatically them into data FLASH.) Don't change your project check link located debug folder that coefficient table crosses boundary data RAM. your project MyProject.mcp, will find file MyProject.elf.xMAP debug daughter folder your Codewarrior project.) Dynamically allocate coefficient tables (out internal memory heap space) modify linker command file, breaking heap space crossing boundary into separate pieces memory. Statically allocate coefficient tables that don't have worry about location them heap space. Then modify linker command file that coefficient tables equivalent) cross boundary data RAM. (This require moving coefficients into separate source files.) Define coefficient tables local variables that they allocated stack space. Verify that stack space defined linker command file) does cross boundary. (This approach don't filtering filters relatively short.) other instruction between sequential accesses.

Errata Number 13.8 Description Problem with Automatic Fault Clearing feature block explained below. fault pins used disable output pins. output pins enabled automatically when fault returns logic zero half cycle begins FMODEx control logic one. only issue with this fault protection mechanism that when fault returns logic zero, channel enabled next clock cycle instead next half cycle. Note that channel always enabled manually after disabled FMODEx logic zero described User's Manual. Impact Work Around Impact: automatic fault clearing used cycle cycle current limiting. This requires cycle-based fault input control. this issue fault input continuously changes voltage thus making difficult output devices respond.
Work Around: None

Errata Number 14.13 Description MSCAN extended rejected STUFF between ID16 ID15. Impact Work Around Impact: 32-bit 16-bit identifier acceptance modes, extended frame with stuff between ID16 ID15 erroneously rejected, depending IDAR0, IDAR1, IDMR1.

When affected received, incorrect value compared byte filter (IDAR1 IDAR5, plus IDAR3 IDAR7 16-bit mode). This incorrect value shift register contents before ID15 shifted (i.e. right shifted Work Around: problematic cannot avoided, workaround mask certain bits with IDMR1 (and IDMR5, plus IDMR3 IDMR7 16-bit mode). Example receive message xxxx xxxx x011 111x xxxx xxxx xxxx xxxx IDMR1 etc. must 111x xxx1, i.e. ID20,19,18,15 must masked. Example receive message xxxx 0111 1111 111x xxxx xxxx xxxx xxxx IDMR1 etc. must 1xxx xxx1, i.e. ID20 ID15 must masked. general, using IDMR1 etc. 1111 xxx1, i.e. masking ID20,19,18,SRR,15, hides problem.
