Operation:

(B) + (M) + C

⇒ B

Description:

Adds the content of accumulator B to the content of memory location M,

then adds the value of the C bit and places the result in B. This instruction

affects the H status bit, so it is suitable for use in BCD arithmetic operations.

See DAA instruction for additional information.

H: X3

• M3 + M3 • R3 + R3 • X3

Set if there was a carry from bit 3; cleared otherwise

N: Set if MSB of result is set; cleared otherwise

Z: Set if result is $00; cleared otherwise

V: X7

• M7 • R7 + X7 • M7 • R7

Set if two’s complement overflow resulted from the operation;

cleared otherwise

C: X7

• M7 + M7 • R7 + R7 • X7
