sla

Operands

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

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

Variants

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