INTERRUPTS
Interrupts caused different sources consisting external, internal, software, reset. Interrupts vectored interrupts with priorities shown Table Reset also included table because operation similar interrupt. When interrupt accepted, contents program counter processor status register automatically stored into stack. interrupt disable flag corresponding interrupt request "0." jump destination address stored vector address enters program counter. Other interrupts disabled when interrupt disable flag "1." interrupts except instruction interrupt have interrupt request interrupt enable bit. interrupt request bits interrupt request registers interrupt enable bits interrupt control registers Figures show interrupt-related registers. Interrupts other than instruction interrupt reset accepted when interrupt enable "1," interrupt request "1," interrupt disable flag "0." interrupt request program, "1." interrupt enable program. Reset treated non-maskable interrupt with highest priority. Figure shows interrupt control.
Interrupt Causes
VSYNC interrupts VSYNC interrupt interrupt request synchronized with vertical sync signal. interrupt occurs after character block display completed. INT1, INT2, INT3 interrupts With external interrupt input, system detects that level changes from from "L," generates interrupt request. input active edge selected bits interrupt input polarity register (address 00F9 when this "0," change from detected; when "1," change from detected. Note that bits cleared reset. Timer interrupts interrupt generated overflow timer Serial interrupt This interrupt request from clock synchronous serial function.

Internal clock: serial counter during write cycle into serial register (address 00DD16), transfer clock goes forcibly. each falling edge transfer clock after write cycle, serial data output from SOUT pin. Transfer direction selected serial mode register. each rising edge transfer clock, data input from data serial register shifted bit. After transfer clock counted times, serial counter becomes transfer clock stops HIGH. this time interrupt request "1." External clock: When external clock selected clock source, interrupt request after transfer clock been counted counts. However, transfer operation does stop, clock should controlled externally. external clock 1MHz less with duty cycle 50%. serial timing shown Figure When using external clock transfer, external clock must held HIGH initializing serial counter. When switching between internal clock external clock, switch during transfer. Also, sure initialize serial counter after switching. Notes programming, note that serial counter writing serial register with managing instructions, such CLB. When external clock used synchronous clock, write transmit data serial register when transfer clock input level HIGH.

OUTPUT FUNCTION
M37224M3-XXXSP equipped with 14-bit (DA) 8-bit PWMs (PWM0-PWM5). 14-bit resolution with minimum resolution width 0.25 repeat period 4096 (for f(XIN) MHz). PWM0-PWM5 have same circuit structure 8-bit resolution with minimum resolution width repeat period 1024 (for f(XIN) MHz). Figure shows block diagram. timing generating circuit applies individual control signals PWM0-PWM5 using f(XIN) divided reference signal.
Operating 14-bit
with 8-bit PWM, output control register (address 00D516) reset, already automatically), that count source supplied. Next, select output polarity output control register (address 00D616). Then, 14-bit outputs from output setting output control register reset, this already automatically) select output. output example 14-bit shown Figure 14-bit divides data latch into low-order bits high-order bits. fundamental waveform determined with high-order 8-bit data "DH." level area with length DH("H" level area fundamental waveform) output every short area minimum resolution width 0.25 µs). level area increase interval (tm) determined with low-order 6-bit data "DL." level smaller intervals "tm" shown Table longer than that other smaller intervals repeat period 64t. Thus, rectangular waveform with different width output from pin. Accordingly, output changes unit pulse width changing contents DA-H DA-L registers. length entirely output cannot output, 256/ 256.
Data Setting
When outputting first high-order bits DA-H register (address 00CE16), then low-order bits DA-L register (address 00CF16). When outputting PWM0-PWM5, 8-bit output data PWMi register means addresses 00D016 00D416, 00F616).
Transmitting Data from Register circuit
Data transfer from 8-bit register 8-bit circuit executed writing data register. signal output from 8-bit output corresponds contents this register. Also, data transfer from register (addresses 00CE16 00CF16) 14-bit circuit executed writing data DA-L register (address 00CF16). Reading from DA-H register (address 00CE16) means reading this transferred data. Accordingly, possible confirm data being output from output reading register.
Output after Reset
reset output port P00-P05 high-impedance state, contents register circuit undefined. Note that after reset, output undefined until setting register.
Operating 8-bit
following explains operation. First, output control register (address 00D516) reset, this already automatically), that count source supplied. PWM0-PWM5 also used pins P00-P05 respectively. PWM0-PWM5, corresponding bits port direction register (output mode). select each output polarity output control register 2(address 00D616). Then, bits output control register (PWM output). waveform output from output pins setting these registers. Figure shows 8-bit timing. cycle composed (28) segments. kinds pulses, relative weight each (bits output inside circuit during cycle. Refer Figure (a). 8-bit outputs waveform performed operation pulses corresponding contents bits 8-bit register. Several examples shown Figure (b). kinds output (HIGH area: 0/256 255/256) selected changing contents register. length entirely HIGH cannot output, i.e. 256/256.
