EUSART RECEIVE BLOCK DIAGRAM

The operation of the EUSART module is controlled

through three registers:

• Transmit Status and Control (TXxSTA)

• Receive Status and Control (RCxSTA)

• Baud Rate Control (BAUDxCON)

These

registers

are

detailed

For all modes of EUSART operation, the TRIS control

bits corresponding to the RXx/DTx and TXx/CKx pins

should be set to ‘1’. The EUSART control will

automatically reconfigure the pin from input to output, as

needed.

When the receiver or transmitter section is not enabled

then the corresponding RXx/DTx or TXx/CKx pin may be

used for general purpose input and output.
