5.5.4 Set Digital Output Port or Write Digital I/O Port
| Firmware Version 1.0 | Firmware Version 1.2 and Later |
|---|---|
|O,<hex16>,<hex16> |
|
Note: All firmware version 1.0 syntax remains valid in version 1.2 and later. | |
Command |O or WIO sets the output value of the digital I/O ports. It expects two input parameters. The first parameter is the bitmap of digital I/O ports, and the second parameter is the output value in the bitmap. The bitmap format is the same as in command |I or QIO (see Table 5-76). If the set GPIO pin is occupied by a function pin whose function is enabled, it will reply to an error response.
