INTERRUPTS (Cont’d)
Table 7. 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.
Table 8. Interrupt Mapping
Note 1. Valid for HALT and ACTIVE-HALT modes except for the MCC/RTC or CSS interrupt source which exits from
ACTIVE-HALT mode only.
