location (HL) are copied to the low order four bits of the Accumulator
(register A). The previous contents of the low order four bits of the
Accumulator are copied to the high order four bits (7, 6, 5, and 4) of
location (HL); and the previous contents of the high order four bits of (HL)
are copied to the low order four bits of (HL). The contents of the high order
bits of the Accumulator are unaffected.
(HL) means the memory location specified by the contents of the HL
register pair.
S is set if Accumulator is negative after operation; reset otherwise
Z is set if Accumulator is zero after operation; reset otherwise
H is reset
P/V is set if parity of Accumulator is even after operation; reset otherwise
N is reset
C is not affected
