srl

Operands

srl r | srl (rr) | srl (ii+dd),r | srl (ii+dd)

The contents of B are shifted right one bit position. The contents of bit 0 are copied to the carry flag and a zero is put into bit 7.

Variants

Every form of srl the assembler accepts. The cycles column counts clock cycles, written as taken/not taken for the conditional forms.
