Prv. bit = HET[0] Pin level; (Always executed)
Shift Immediate Data Field once according to P[3:0];
Immediate Data Field = Result of the shift;
Selected register = Result of the shift;
Jump to Next Program Address;
NOTE: The immediate data field evaluates all 0s or all 1s and is performed before the shift
operation.
The specific interrupt flag that is triggered depends on the address from which the instruction is executed,
see Section 23.2.7.
