OUT = Output, IN = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input,
TTL = TTL Buffer Input, XCVR = USB transceiver, x = Don’t care (TRIS bit does not affect port direction or is overridden
for this option)
Default pin assignment. Alternate pin assignment is RB3 (when CCP2MX = 0).
RC4 and RC5 do not have corresponding TRISC bits. In Port mode, these pins are input only. USB data direction is
determined by the USB configuration.
40/44-pin devices only.
