Note An on-chip pull-up resistor can be connected only when the pins are in input mode in the port mode.
Remark
(d) Pull-up resistor option register 2 (PU2)
Moreover, an on-chip pull-up resistor can only be connected to the TOQ1T1 to TOQ1T3, TOQ1B1 to
TOQ1B3, and TOP31 pins, these pins are output pins in the alternate-function mode, when these pins go
into a high-impedance state due to the TOQ1OFF or TOP3OFF pin, or software processing. An on-chip
pull-up resistor cannot be connected when the pins are in output mode.
