MAXD – Maximum between Data Memory Location and
Accumulator
Syntax:
maxd aX, (r0), ge|gt
Operation:
When using
ge:
If (r0)
≥ aX, then
(r0) –> aX
r0 –> mixp
r0 is post-modified as specified.
When using
gt:
If (r0) > aX, then
(r0) –> aX
r0 –> mixp
r0 is post-modified as specified.
This instruction is used to find the maximal value between a data mem-
ory location pointed to by r0 and one of the aX-accumulators. In case r0
points to a larger (or larger or equal) value than the accumulator, the
new maximal is transferred in the specified accumulator (aX) and the r0
pointer is transferred in the mixp register. The r0 register is post-modi-
fied as specified in the instruction, regardless of whether the new maxi-
mal value is updated.
Affected Flags:
M is set when the maximum value is found and the accumulator and
mixp register are updated. Cleared otherwise.
Cycles:
1
Words:
1
Notes:
mixp cannot be read in the instruction following the
maxd instruction.
