Decoupling Capacitors
decoupling capacitors every pair power supply pins, such VDD, VSS, AVDD AVSS required. Consider following criteria when using decoupling capacitors: Value type capacitor: Recommendation (100 nF), 10-20V. This capacitor should low-ESR have resonance frequency range higher. recommended that ceramic capacitors used. Placement printed circuit board: decoupling capacitors should placed close pins possible. recommended place capacitors same side board microcontroller. space constricted, capacitor placed another layer using via; however, ensure that trace length from capacitor within one-quarter inch length. Handling high frequency noise: board experiencing high frequency noise, upward tens MHz, second ceramic-type capacitor parallel above described decoupling capacitor. value second capacitor range 0.01 0.001 Place this second capacitor next primary decoupling capacitor. high-speed circuit designs, consider implementing decade pair capacitances close power ground pins possible. example, parallel with 0.001 Maximizing performance: board layout from power supply circuit, power return traces decoupling capacitors first, then microcontroller pins. This ensures that decoupling capacitors first power chain. Equally important keep trace length between capacitor power pins minimum thereby reducing track inductance.

Stack Pointer always points first available free word grows from lower higher addresses. pre-decrements stack pops post-increments stack pushes, shown Figure 4-4. push during CALL instruction, zero-extended before push, ensuring that always clear. Note: push during exception processing concatenates register prior push. PIC24H product family supports Data protection features that enable segments protected when used conjunction with Boot Secure Code Segment Security. BSRAM (Secure segment accessible only from Boot Segment Flash code when enabled. SSRAM (Secure segment RAM) accessible only from Secure Segment Flash code when enabled. Table overview BSRAM SSRAM SFRs.
Instruction Addressing Modes
Stack Pointer Limit register (SPLIM) associated with Stack Pointer sets upper address boundary stack. SPLIM uninitialized Reset. Similarly, Stack Pointer, SPLIM<0> forced because stack operations must word aligned. When generated using source destination pointer, resulting address compared with value SPLIM. contents Stack Pointer (W15) SPLIM register equal push operation performed, stack error trap will occur. stack error trap will occur subsequent push operation. example, cause stack error trap when stack grows beyond address 0x1000 RAM, initialize SPLIM with value 0x0FFE. Similarly, Stack Pointer underflow (stack error) trap generated when Stack Pointer address found lesser than 0x0800. This prevents stack from interfering with Special Function Register (SFR) space. write SPLIM register should immediately followed indirect read operation using W15.

Since address ranges data program spaces bits, respectively, method needed create 23-bit 24-bit program address from 16-bit data registers. solution depends interface method used. table operations, 8-bit Table Page register (TBLPAG) used define word region within program space. This concatenated with 16-bit arrive full 24-bit program space address. this format, Most Significant TBLPAG used determine operation occurs user memory (TBLPAG<7> configuration memory (TBLPAG<7> remapping operations, 8-bit Program Space Visibility register (PSVPAG) used define word page program space. When Most Significant `1', PSVPAG concatenated with lower bits form 23-bit program space address. Unlike table operations, this limits remapping operations strictly user memory area. Table 4-24 Figure show program created table operations remapping accesses from data Here, P<23:0> refers program space word, D<15:0> refers data space word.
PIC24HJ32GP202/204 PIC24HJ16GP304 architecture uses 24-bit-wide program space 16-bit wide data space. architecture also modified Harvard scheme, which means that data also present program space. this data successfully, must accessed that preserves alignment information both spaces. Aside from normal execution, PIC24HJ32GP202/204 PIC24HJ16GP304 architecture provides methods which program space accessed during operation: Using table instructions access individual bytes words anywhere program space Remapping portion program space into data space (Program Space Visibility) Table instructions allow application read write small areas program memory. This capability makes method ideal accessing data tables that need updated periodically. also allows access bytes program word. remapping method allows application access large block data read-only basis, which ideal look from large table static data. application only access least significant word program word.

PIC24HJ32GP202/204 PIC24HJ16GP304 devices implement total registers interrupt controller: Interrupt Control Register (INTCON1) Interrupt Control Register (INTCON2) Interrupt Flag Status Registers (IFSx) Interrupt Enable Control Registers (IECx) Interrupt Priority Control Registers (IPCx) Interrupt Control Status Register (INTTREG)
7.3.5
INTTREG
INTTREG register contains associated interrupt vector number interrupt priority level, which latched into vector number (VECNUM<6:0>) Interrupt level (ILR<3:0>) fields INTTREG register. interrupt priority level priority pending interrupt. interrupt sources assigned IFSx, IECx IPCx registers same sequence that they listed Table 7-1. example, INT0 (External Interrupt shown having vector number natural order priority Thus, INT0IF found IFS0<0>, INT0IE IEC0<0>, INT0IP bits first position IPC0 (IPC0<2:0>).
7.3.1
INTCON1 INTCON2
Global interrupt control functions controlled from INTCON1 INTCON2. INTCON1 contains Interrupt Nesting Disable (NSTDIS) well control status flags processor trap sources. INTCON2 register controls external interrupt request signal behavior Alternate Interrupt Vector Table.
7.3.6
STATUS REGISTERS
7.3.2
IFSx
registers maintain interrupt request flags. Each source interrupt status bit, which respective peripherals external signal this cleared software.
Although these specifically part interrupt control hardware, Control registers contain bits that control interrupt functionality: STATUS register, contains IPL<2:0> bits (SR<7:5>). These bits indicate current interrupt priority level. user change current priority level writing bits. CORCON register contains IPL3 which, together with IPL<2:0>, also indicates current priority level. IPL3 read-only bit, that trap events cannot masked user software. Interrupt registers described Register through Register 7-19 following pages.
7.3.3
IECx
registers maintain interrupt enable bits. These control bits used individually enable interrupts from peripherals external signals.
