P
instruction) has a transition from 0 to 1, will rotate the data of D
register towards the left by N successive bits (in ascending order, ie. in a 16-bit instruction, B0
→
B1, B1
→
B2, .... , B14
→
B15, B15
→
B0. In a 32-bit instruction, B0
→
B1, B1
→
B2, .... , B30
→
B31, B31
→
B0). At the
same time, the status of the rotated out bits B15 or B31 (
D
instruction) will appear at rotate-out bit "OTB".
z
If the operand is 16 bit, the effective range of N is 1~16. For 32 bits (
D
instruction) operand, it is 1~32.
Beyond this range, will set the N value error flag "ERR" to 1, and do not carry out this instruction.
