40 / 191 page ![]() ST72340, ST72344, ST72345 40/191 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 Notes: 1. Valid for HALT and ACTIVE-HALT modes except for the MCC/RTC interrupt source which exits from ACTIVE-HALT mode only and AWU interrupt which exits from AWUFH mode only. 2. Exit from HALT possible when SPI is in slave mode.
