Stopping and Starting the Receiver
To stop the receiver, the host must clear the RXEN bit in the
When the receiver is halted, the RXSTOP_INT will be pulsed and reflected in the
Register
The host must re-enable the receiver by setting the RXEN bit.
Receiver Errors
If the Receiver Error (RXE) flag is asserted in the
the receiver will continue operation. RX Error (RXE) will be asserted under the following conditions:
It is the duty of the host to identify and resolve any error conditions.
A host underrun of RX Data FIFO
A host underrun of the RX Status FIFO
An overrun of the RX Status FIFO
(INT_STS). Once stopped, the host can optionally clear the RX Status and RX Data FIFOs.
