INTERRUPTS (Cont’d)
Table 6. Dedicated Interrupt Instruction Set
Note: During the execution of an interrupt routine, the HALT, POPCC, RIM, SIM and WFI instructions change the current
software priority up to the next IRET instruction or one of the previously mentioned instructions.
In order not to lose the current software priority level, the RIM, SIM, HALT, WFI and POP CC instructions should never
be used in an interrupt routine.
