Hex	Mnemonic	Cycles
CE 94	RLC A	3
CE 95	RLC B	3
CE 96 ll	RLC [BR:ll]	5
CE 97	RLC [HL]	4

Execute

A       = Register A
B       = Register B
[BR:ll] = Memory: (EP shl 16) or (BR shl 8) or #nn
[HL]    = Memory: (EP shl 16) or HL

; RLC Ds
;
; Ds = Source/Destination

Ds = (Ds SLL 1) OR (Ds SRL 7)

Description

“8-bits Destination” bits are rotated left by 1.

Conditions

• Zero: Set when result is 0
• Carry: Set when bit 0 of the result is 1
• Negative: Set when bit 7 of the result is 1

Overflow remains unchanged

Examples

; A = 0x04
RLC A
; A = 0x08
; SC = (Zero=0):(Carry=0):(Negative=0)

; B = 0x45
RLC B
; B = 0x8A
; SC = (Zero=0):(Carry=0):(Negative=1)

; B = 0x84
RLC B
; B = 0x15
; SC = (Zero=0):(Carry=1):(Negative=0)

; [HL] = 0x80
RLC [HL]
; [HL] = 0x01
; SC = (Zero=0):(Carry=1):(Negative=0)
