Enabling the Receiver

The EUSART receiver is enabled for asynchronous operation by configuring the following three control bits:

All other EUSART control bits are assumed to be in their default state.

The user must set the RXxPPS register to select the RXx/DTx I/O pin and set the corresponding TRIS bit to configure the pin as an input.

Important: If the RX/DT function is on an analog pin, the corresponding ANSEL bit must be cleared for the receiver to function.
