The input buffer is always active, except in analog mode. This means that the Port B input should be a valid digital
value at all times unless the pin is set in analog mode. Violating this rule may lead to high power consumption.
12.7.2
Note 1: this value is indicative only since it depends on the package.
12.8 Low power comparators
If the low power comparator (CMPD) peripheral is present in the circuit, the signals on the pins PB[7:4] can be used
as inputs for these low power comparators. Although the comparators are functional independent of the Port B
configuration, it is recommended to set the pins that are used for the CMPD in analog mode without selecting any
analog lines. This to avoid high power consumption in the digital input buffer when analog or slowly varying digital
signals are applied.
