    PORTC, TRISC and LATC
    Registers
    PORTC is an 8-bit wide, bidirectional port. The corre-
    sponding data direction register is TRISC. Setting a
    TRISC bit (= 1) will make the corresponding PORTC
    pin an input (i.e., put the corresponding output driver in
    a high-impedance mode). Clearing a TRISC bit (= 0)
    will make the corresponding PORTC pin an output (i.e.,
    put the contents of the output latch on the selected pin).
    The Data Latch register (LATC) is also memory
    mapped. Read-modify-write operations on the LATC
    register, read and write the latched output value for
    PORTC.
    PORTC is multiplexed with several peripheral functions
    (Table 10-5). PORTC pins have Schmitt Trigger input
    buffers.
    When enabling peripheral functions, care should be
    taken in defining TRIS bits for each PORTC pin. Some
    peripherals override the TRIS bit to make a pin an
    output, while other peripherals override the TRIS bit to
    make a pin an input. The user should refer to the
    corresponding peripheral section for the correct TRIS
    bit settings.
    The pin override value is not loaded into the TRIS
    register. This allows read-modify-write of the TRIS
    register, without concern due to peripheral overrides.
    RC1 is normally configured by configuration bit,
    CCP2MX, as the default peripheral pin of the CCP2
    module (default/erased state, CCP2MX = 1).
