The byte at memory address specified by the contents of the HL register pair is compared with the contents of the Accumulator. If there is a true compare, the Z flag is set. The execution of this instruction does not affect the contents of the Accumulator.
S | is set if result is negative, otherwise it is reset. |
Z | is set if result is 0, otherwise it is reset. |
H | is set if borrow from bit 4, otherwise it is reset. |
P/V | is set if overflow, otherwise it is reset |
N | is set. |
C | is set if borrow, otherwise it is reset. |
If the Accumulator contains $63, register pair HL contains $2323, and memory location $2323 contains byte $60, then upon the execution of
CP (HL)
the P/V flag in the F Register is reset.
