Note An on-chip pull-up resistor can be connected only when the pins are in input mode in the port mode or
Remark
(g) Pull-up resistor option register 2 (PU2)
when the pins function as input pins in the alternate-function mode. Moreover, an on-chip pull-up
resistor can be connected to the TOB1T1 to TOB1T3 and TOB1B1 to TOB1B3 pins, these are output
pins in the alternate-function mode, when these pins go into a high-impedance state due to the
TOB1OFF pin, or software processing. An on-chip pull-up resistor cannot be connected when the pins
are in output mode.
