Description

RC7/RX/DT/SDO RC7

0

O

DIG LATC<7> data output.

1

I

ST PORTC<7> data input.

RX

1

I

ST Asynchronous serial receive data input (EUSART module).

DT

0

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.

SDO(1)

0

O

DIG SPI data out; takes priority over port data.

Legend:

Note 1:

DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level input/output;

x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).

RD0 is the alternate pin for T0CKI/T5CKI; RD2 is the alternate pin for SDI/SDA; RD3 is the alternate pin for SCK/SCL;

RD1 is the alternate pin for SDO.
