Note 1. Can be modified only once after a reset.
The POECMPSEL register sets a comparator output detection flag to use as a control condition to put the outputs in the
high-impedance state.
POEREQn Bit (Comparator Channel n High-Impedance Request Enable) (n = 0 to 2)
This bit disables or enables high-impedance request generation in response to each comparator output detection. A high-
impedance request is generated when one of the comparator outputs is detected.
