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

Description
Decimal-Adjust accumulator for addition
The accumulator value is adjusted to the BCD (Binary Code Decimal) code.
The accumulator is divided into two nibbles. E ach nibble is adjusted to the
BCD code and an internal carry (AC1) will be created if the low nibble of the
accumulator is greater than 9. The BCD adjustment is done by adding 6 to
the original 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.
If (ACC.3~ACC.0) >9 or AC=1
then ([m].3~[m].0)

(ACC.3~ACC.0)+6, AC1=AC
