Цитата:
1.2) CB Prefix [1]
An opcode with a CBh prefix is a rotate, shift or bit test/set/reset
instruction. There are a few instructions missing from the official list,
which are usually denoted with SLL (Shift Logical Left). It works like
SLA, for one exception: it sets bit 0 (SLA resets it).
CB30 SLL B
CB31 SLL C
CB32 SLL D
CB33 SLL E
CB34 SLL H
CB35 SLL L
CB36 SLL (HL)
CB37 SLL A
