POPF, to support the eight additional
interrupts. It pops two words off the stack and
places the first word into the
INT_MASK1/WSR register pair and the
second word into the PSW/INT_MASK
register-pair. This instruction increments the
SP by 4. Interrupt-calls cannot occur
immediately following this instruction.
