Note 1: I/O pin has diode protection to V
2: To enable weak pull-ups, set the appropriate TRIS bit(s) and clear the RBPU bit (OPTION_REG<7>).
2: To enable weak pull-ups, set the appropriate DDR bit(s) and clear the RBPU bit (INTCON2<7>).
3: The CCP2 input/output is multiplexed with RB3, if the CCP2MX bit is enabled (=’0’) in the configuration register.
