The R ETI in structio n caus es you to exit fr om O NTI CK , ONT IME (RPC -52 ca rd only ) and O NIT R inte rrupts.
RETI functions like RETURN , but it clears software interrupt flags so that RPBAS IC-52 can acknowledge
subsequent inte rrupts. If you don't execute the RET I instruction in the interrupt proc edure, all future
interrupts, hardware and software, are ignored.
