|Description:||Return from interrupt, compensate RTCC|
|Operation:||PC, W, FSR and status = shadow register; RTCC += lit|
|Registers affected:||RTCC PC|
|Details:||SX Users Manual page # 115|
|Microchip PIC syntax:|
RETIW - Same as RETI but adds the contents of W to RTCC without affecting the prescaler. This provides a periodic interrupt that can be adjusted by 256 steps (minus the time it takes to execute the interrupt routine)
by Loren Blaney via Richard Ottosen
The RETIW instruction ADDS W to RTCC, not subtracts it as stated in Table 16-1 in SX Datasheet page 33
