Compare with memory

The contents  of the memory  of the memory  location  pointed by HL  register pair are compared with the  contents of the accumulator. The  instruction format is

CMP M        (A- [ HL])

The contents  of the both  the operand memory  location  and the  accumulator do not change. The flags  are modified  similar  to subtraction.

Flags : All flags  are modified  but he conclusion can be  made only by CY and  Z flag   as shown  below.

If A> M : CUY and Z flag are reset

IF a = M : Z flag  is set and CY flag is reset.

IF A < M : CY  is set and Z flag is reset.
