PIC18F2XK20/4XK20
FIGURE 18-2:
The operation of the EUSART module is controlled
through three registers:
• Transmit Status and Control (TXSTA)
• Receive Status and Control (RCSTA)
• Baud Rate Control (BAUDCTL)
These
Register 18-2 and Register 18-3, respectively.
For all modes of EUSART operation, the TRIS control
bits corresponding to the RX/DT and TX/CK pins should
be set to ‘1’. The EUSART control will automatically
reconfigure the pin from input to output, as needed.
