SB — Set I/O output bits
Usage IMM PGM MIP
Syntax xxSBnn
Parameters
Description xx [int] — I/O bit number.
nn [int] — I/O bit mask.
Valeurs xx — 0 to 8.
nn — 0 to 255.
Units xx — None.
nn — None.
Defaults xx Missing: 0.
Out of range: Error E.
Floating point: Error A.
nn Missing: 255.
Out of range: Error C.
Floating point: Decimal part truncated.
Description This command sets one to all output bits of the I/O port. If xx is specified
between 1 and 8, the nn mask must be missing and then the selected bit
will be set.
If
xx is missing or set to 0 and nn is between 1 and 255, the controller will
set all bits corresponding to the mask. For example, if nn is 140, the equiva-
lent binary mask is 10001100 which means that I/O output bits number 3, 4
and 8 will be set (remember that I/O bits are numbered from 1 to 8).
If
xx is missing or set to 0 and nn is not specified, the controller sets all 8
bits. This is equivalent to setting xx to 0 and nn to 255.
NOTE
Remember that having an open collector configuration, a set bit means a
conducting transistor. Using a pull-up resistor, a set output bit will mea-
sure a logic low, thus making the output port be the reverse logic type.
NOTE
For the hardware definition of the I/O port, please see Appendix B,
Connector Pinouts, GPIO Connector.
Returns None.
Errors A — Unknown message code.
E — Incorrect I/O channel number.
Rel. Commands CB — Clear I/O outputs bits.
RO — Read I/O output.
SO — Set I/O output byte.
TG — Toggle I/O output bits.
Example SB224 | Set I/O output port bits number 6, 7 and 8 high.
