Syntax x x S B n n
Parameters
Description x x [ i n t ] — I / O bit number.
nn [ i n t ] — I / O bit mask.
Range x x 0 to 8.
nn 0 to 255.
Units x x N o n e .
nn N o n e .
Defaults x x M i s s i n g : 0 .
Out of range: E r r o r E.
Floating point: E r r o r A.
nn M i s s i n g : 255.
Out of range: E r r o r C.
Floating point: Decimal part truncated.
Description T h i s 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.
