sspplloo() -- Interrupt-Handler Routine

sspplloo()

sspplloo() enables hardware interrupts.   It returns a value that describes the
previous  hardware  interrupt state.   Using  sspplloo()  to enable  interrupts
unconditionally is  undesirable, and may  indeed corrupt the  system state.
Use ssppll() to return to the previous interrupt mask level.
