RC7/RX1/DT1/
SEG28
RC7 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.
