rlc

Operands

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

The contents of B are rotated left one bit position. The contents of bit 7 are copied to the carry flag and bit 0.

Variants

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