1010 SB – Set the specified bit. The port number. Result (OK or ERROR).
1011 XB – Exclusive Or the specified bit. The port number. Result (OK or ERROR).
1100 MFR – Monostable function, start with the speci-
fied bit in OFF state (reset).
The port number,
the OFF and the
ON times (in sec-
onds), both as 16-
bit integers.
Result (OK or ERROR)
1101 MFS – Monostable function, start with the speci-
fied bit in ON state (set).
The port number,
the OFF and the
ON times (in sec-
onds), both as 16-
bit integers.
Result (OK or ERROR).
1110 MVFR – Multivibrator function, start with the
specified bit in OFF state (reset).
The port number,
the OFF and the
ON times (in sec-
onds), both as 16-
bit integers.
Result (OK or ERROR).
