FIGURE 16-2:
The operation of the EUSART module is controlled
through three registers:
• Transmit Status and Control (TXSTAx)
• Receive Status and Control (RCSTAx)
• Baud Rate Control (BAUDCONx)
These
Register 16-2
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.
