Flags: N:
If the contents of the accumulator are determined to be less then 0 (a negative number),
the absolute value of the accumulator is calculated (accumulator replaced by its two’s
complement value). Using the condition code provides an additional method to evaluate a
status flag before the absolute value of the accumulator is calculated.
Initialization:
Instruction:
Result:
This example uses one word of memory and executes in one machine cycle. Because the
value in the accumulator is less then zero, the two’s complement is performed and the
result is placed in the accumulator ABS(FFEBH)=001500H. The carry bit is set.
ABS <cc>, A
ABS A
If ACC < 0 then -(ACC) -> ACC
ABS A
If the accumulator contains 800000H, the ABS A instruction stores the value of
the two’s complement at address 800000H and sets the Overflow and Negative
status bits. There is no overflow protection.
Set if the accumulator has 800000H (see below).
Accumulator contains FFEB00H
SR contains 0000H
ABS A
Accumulator contains 001500H
SR contains 1000H
