Hex	Mnemonic	Cycles
CE D8	MLT	48

Execute

; MLT
;
; L is the Factor/Multiplicand
; A is the Multiplier
; HL will be the Product

HL = L x A

Description

Multiply “8-bits Register L” by “8-bits Register A”, 16-bits result is placed in “16-bits Register HL”.

Conditions

• Zero: Set when result is 0
• Carry: Always reset
• Overflow: Always reset
• Negative: Set when bit 15 of the result is 1

Examples

; A = 0x03
; L = 0x03
MLT
; A = 0x03
; HL = 0x0009 (0x03 * 0x03 = 0x0009)
; SC = (Zero=0):(Carry=0):(Overflow=0):(Negative=0)

; A = 0x00
; L = 0x03
MLT
; A = 0x00
; HL = 0x0000 (0x03 * 0x00 = 0x0000)
; SC = (Zero=1):(Carry=0):(Overflow=0):(Negative=0)

; A = 0xFF
; L = 0xFF
MLT
; A = 0xFF
; HL = 0xFE01 (0xFF * 0xFF = 0xFE01)
; SC = (Zero=0):(Carry=0):(Overflow=0):(Negative=1)
