Operation:
Description: Suspend normal instruction execution and begin SWI exception process-
ing. The interrupt priority level (I1,I0) is set to 3 in the status register (SR) if a long inter-
rupt service routine is used.
Restrictions:
An SWI instruction cannot be used in a fast interrupt routine.
An SWI instruction cannot be repeated using the REP instruction.
