PORTB and the TRISB Register
PORTB is an 8-bit wide bi-directional port. The corresponding data direction register is TRISB.
Setting a bit in the TRISB register puts the corresponding output driver in a high-impedance input
mode. Clearing a bit in the TRISB register puts the contents of the output latch on the selected
pin(s).
Example 9-2:
Each of the PORTB pins has a weak internal pull-up. A single control bit can turn on all the
pull-ups. This is performed by clearing bit RBPU (OPTION<7>). The weak pull-up is automati-
cally turned off when the port pin is configured as an output. The pull-ups are disabled on a
Power-on Reset.
