; ADC Ds, Sc ; ; Ds = Destination ; Sc = Source Ds = Ds + Sc + Carry
Description
16-Bits Source and Carry adds to the 16-Bits Destination.
Conditions
Zero: Set when result is 0
Carry: Set when result is >= 65536
Overflow: Set when result overflow 16-bits signed range (< -32768 OR > 32767)
Sign: Set when bit 15 of the result is 1
Examples
; BA = 0x0EF0 ; F = (Carry=1) ADC BA, $1337 ; BA = 0x2228 (0x0EF0 + 0x1337 + 0x0001 = 0x(0)2228) ; F = (Zero=0):(Carry=0):(Overflow=0):(Sign=0)
; HL = 0xBB7E ; BA = 0xCF12 ; F = (Carry=0) ADC BA, HL ; HL = 0xBB7E ; BA = 0x8A90 (0xCF12 + 0xBB7E + 0x0000 = 0x(1)8A90) ; F = (Zero=0):(Carry=1):(Overflow=0):(Sign=1)
; X = 0xBEEF ; BA = 0xDEAD ; F = (Carry=1) ADC BA, X ; X = 0xBEEF ; BA = 0x9D9D (0xDEAD + 0xBEEF + 0x0001 = 0x(1)9D9D) ; F = (Zero=0):(Carry=1):(Overflow=1):(Sign=0)
