CNPUE<21:0>: CNPUE Register bits
If a port pin is configured as an input (corresponding TRISx bit = 1).
1 = Port pin pull-up enabled
0 = Port pin pull-up disabled
If a port pin is configured as an output, it is recommended to disable the corresponding CNPUEx bit.
Note 1: Depending on the device, certain register bits or the entire register may not be implemented. Refer to
Table 12.1 for specific register and bit assignments.
