I/O pin has diode protection to V
To enable weak pull-ups, set the appropriate TRIS bit(s) and clear the RBPU bit (INTCON2<7>).
For PIC18F8525/8621 parts, the ECCP2 input/output is multiplexed with RB3 if the CCP2MX bit is enabled (= 0)
in the Configuration register and the device is operating in Microprocessor, Microprocessor with Boot Block or
Extended Microcontroller mode.
