LCPL [m]
Complement Data Memory
Description Each bit of the specied Data Memory is logically complemented (1′s complement). Bits which
previously contained a 1 are changed to 0 and vice versa.
Operation [m] ← [m]
Affected ag(s) Z
LCPLA [m]
Complement Data Memory with result in ACC
Description Each bit of the specied Data Memory is logically complemented (1′s complement). 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.
Operation ACC ← [m]
Affected ag(s) Z
LDAA [m]
Decimal-Adjust ACC for addition with result in Data Memory
Description Convert the contents of the Accumulator value to a BCD (Binary Coded Decimal) value
resulting from the previous addition of two BCD variables. If the low nibble is greater than 9
or if AC ag is set, then a value of 6 will be added to the low nibble. Otherwise the low nibble
remains unchanged. If the high nibble is greater than 9 or if the C ag is set, then a value of 6
will be added to the high nibble. Essentially, the decimal conversion is performed by adding
00H, 06H, 60H or 66H depending on the Accumulator and ag conditions. Only the C ag
may be affected by this instruction which indicates that if the original BCD sum is greater than
100, it allows multiple precision decimal addition.
Operation [m] ← ACC + 00H or
[m] ← ACC + 06H or
[m] ← ACC + 60H or
[m] ← ACC + 66H
Affected ag(s) C
LDEC [m]
Decrement Data Memory
Description Data in the specied Data Memory is decremented by 1.
Operation [m] ← [m] − 1
Affected ag(s) Z
LDECA [m]
Decrement Data Memory with result in ACC
Description Data in the specied Data Memory is decremented by 1. The result is stored in the
Accumulator. The contents of the Data Memory remain unchanged.
Operation ACC ← [m] − 1
Affected ag(s) Z
LINC [m]
Increment Data Memory
Description Data in the specied Data Memory is incremented by 1.
Operation [m] ← [m] + 1
Affected ag(s) Z
LINCA [m]
Increment Data Memory with result in ACC
Description Data in the specied Data Memory is incremented by 1. The result is stored in the Accumulator.
The contents of the Data Memory remain unchanged.
Operation ACC ← [m] + 1
Affected ag(s) Z
