INTERRUPTS (Cont’d)
Table 9. 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.
