Function
Set counter.
Reset counter.
Add two fixed-point numbers:
ACCU 1+ACCU 2.
CC 1/CC 0/OV are affected.
Subtract one fixed-point
number from another:
ACCU 2 - ACCU 1.
CC 1/CC 0/OV are affected.
Compare two fixed-point
numbers for "equal to": If
ACCU 2=ACCU 1, the RLO
is "1".
CC 1/CC 0 are affected.
Compare two fixed-point
numbers for "not equal to": If
ACCU 2 ACCU 1, the RLO
is "1".
CC 1/CC 0 are affected.
Compare two fixed-point
numbers for "greater than":
If ACCU 2 > ACCU 1, the
RLO is "1". CC 1/CC 0 are
affected.
Compare two fixed-point
numbers for "greater than or
equal to": If ACCU 2
ACCU 1, the RLO is "1".
CC 1/CC 0 are affected.
Compare two fixed-point
numbers for "less than":
If ACCU 2 < ACCU 1, the
RLO is "1". CC 1/CC 0 are
affected.
Compare two fixed-point
numbers for "less than or equal
to": If ACCU 2 ACCU 1, the
RLO is "1". CC 1/CC 0 are
affected.
