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