compared with the contents of the Accumulator. In case of a true compare,
a condition bit is set. Then HL is incremented and the Byte Counter
(register pair BC) is decremented.
S is set if result is negative; reset otherwise
Z is set if A is (HL); reset otherwise
H is set if borrow from bit 4; reset otherwise
P/V is set if BC -1 is not 0; reset otherwise
N is set
C is not affected
