1.

Function

Shifts a bit pattern.

2.

Call

3.

Explanation of Parameters

IW (I) Argument of one word length for shifting the bit pattern.

N (I) Number of bits to shift. Shifts to the left when N｡�0. The bits that have overflowed on the left side are filled in on the right (circular shift). Shifts to the right when N<0 The bits that have overflowed on the right are discarded (end-off shift).

ISHIFT (I) The value of a function which returns the result of shifting.
