SWILP
Operation
SWILP
struction to interrupt the execution core, the instruction is ignored and subsequent instructions are
fetched and executed as normal. This instruction does not modify the I1 and I0 interrupt mask bits
when it is processed.
SWILP
Lowest-priority interrupt processing is requested, if the interrupt priority level is set low enough to al-
low it.
The condition codes are not affected by this instruction.
