0
O DIG LATC<7> data output.
1
I
ST PORTC<7> data input.
RX1
1
I
ST Asynchronous serial receive data input (EUSART module).
DT1
1
O DIG Synchronous serial data output (EUSART module); takes priority over port data.
1
I
ST Synchronous serial data input (EUSART module); user must configure as an input.
SEG28
1
O ANA LCD Segment 28 output; disables all other pin functions.
Legend:
Note 1:
O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Trigger Buffer Input, TTL = TTL Buffer Input,
I2C = I2C Buffer Input, x = Donât care (TRIS bit does not affect port direction or is overridden for this option).
Default assignment for ECCP2 when the CCP2MX Configuration bit is set.
