z
When shift control "EN" = 1 or "EN
↑
" (
P
instruction) has a transition from 0 to 1, will shift the data of D
register towards the right by N successive bits (in descending order). After the highest bits, B15 or B31 (
D
instruction) have been shifted right, their positions will be replaced by the shift-in bit INB, while shift-out bit
B0 will appear at shift-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.
