Note
After the W800 is powered on, all IO defaults to Floating and Input status
IO configured as OPT6, 7 o’clock is configured as analog function, do not set pullup at this time, otherwise it may damage the chip
The application layer needs to pay attention to IO configuration, with only one pin func configuration per channel, and maintain only one output channel
When multiple pins are set to the same PWM channel (e.g. GPO2, GPO10 are both set to PWM0), these pins will output
