CPLA [m]
Complement data memory and place result in the accumulator
Description
Each bit of the specified data memory is logically complemented (1 s comple-
ment). Bits which previously contained a 1 are changed to 0 and vice-versa.
The complemented result is stored in the accumulator and the contents of
the data memory remain unchanged.

Decimal-Adjust accumulator for addition
Description
The accumulator value is adjusted to the BCD (Binary Code Decimal) code.
Theaccumulatorisdividedinto2nibbles.EachnibbleisadjustedtotheBCD
code and an internal carry (AC1) will be done if the low nibble of the accumu-
lator is greater than 9. The BCD adjustment is done by adding 6 to the origi-
nal value if the original value is greater than 9 or a carry (AC or C) is set;
otherwise the original value remains unchanged. The result is stored in the
data memory and only the carry flag (C) may be affected.
Operation
If ACC.3~ACC.0 >9 or AC=1
then [m].3~[m].0
else [m].3~[m].0)
and
If ACC.7~ACC.4+AC1 >9 or C=1
then [m].7~[m].4
else [m].7~[m].4
(ACC.3~ACC.0)+6, AC1=AC
