sll

Operands

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

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

Variants

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