64 Start a timer (stored in
ACCU 1) as extended pulse
(signal contracting and
stretching) on the leading edge
of the RLO.
65 Start an on-delay timer (stored
in ACCU 1) on the leading
edge of the RLO.
65 Start a stored on-delay timer
(stored in ACCU 1) on the
leading edge of the RLO.
64 Start an off-delay timer (stored
in ACCU 1) on the trailing edge
of the RLO.
21 Reset a timer.
35 Counter counts up 1 on the
leading edge of the RLO.
40 Counter counts down 1 on
leading edge of the RLO.
62 Set counter if RLO="1".
17 Reset counter if RLO="1".
19 Add two fixed-point numbers:
ACCU 1+ACCU 2.
CC 1 / CC 0 / OV are affected.
22 Subtract one fixed-point
number from another:
ACCU 2 - ACCU 1.
CC 1 / CC 0 / OV are affected.
21 Compare two fixed-point
numbers for "equal to": If
ACCU 2=ACCU 1, the RLO
is "1".
CC 1 / CC 0 are affected.
22 Compare two fixed-point
numbers for "not equal to": If
ACCU 2 ACCU 1, the RLO
is "1".
CC 1 / CC 0 are affected.
