TOUT/POUT output mode
Four output modes are available on the STM8T141:
●
●
●
●
For each output operation described, touch or proximity detection can be used. Upon the
detection of either of these actions, the TOUT/POUT pin will latch high, otherwise the
TOUT/POUT pin stays low. The detailed working of each user interface is described below.
The TOUT/POUT pin is active high, and can source enough current to directly drive a LED.
The pin is sourced from V
minimum time of t
characteristics.
Bits [1:0] of option byte OPT0 are used to select the correct output mode.
Active
Upon the detection of an actuation, the condition of the TOUT/POUT pin will change to high
and stay high for as long as the touch or proximity detection condition occurs.
