STM8T143
6.3
Frame format
The content of the data frame is described in
Table 7.
Output polarity
The polarity can be chosen to define POUT and TOUT active state during a detection event
such as high or low.
When the device is configured in output active low, pin 8 is in open drain configuration.
When the device is configured in output active high, pin 8 is in push-pull configuration.
