27 / 158 page  ST72589BW, ST72389BW 27/158 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. Table 7. Interrupt Mapping Instruction New Description Function/Example I1 H I0 N Z C HALT Entering Halt mode 1 0 IRET Interrupt routine return Pop CC, A, X, PC I1 H I0 N Z C JRM Jump if I1:0=11 I1:0=11 ?
