Device operating modes
The STM8T143 device provides three operating modes:
●
●
●
These modes are selected through the option bytes.
Dual output mode
The device is configured by default in Control mode. The Dual output/Control mode bit
allows the user to configure pin 8 of the device in Control input or Proximity output.
When Dual output mode is selected, pin 8 becomes the proximity output while pin1 is the
touch output.
