Is there a way to disable just the receive portion of a USIC channel running in ASC mode? Our custom board has a 1/2 duplex UART, and it is connected to both the RX and TX lines of one of the USIC channels. The hardware has buffers in line with the TX/RX lines, so we cannot run in half-duplex mode. I have been through the USIC register descriptions in the reference manual, but the only possibility I see is to set DX0CR.DSEL to b111 to keep the input data fixed @ 1.
Is there any way to just turn off the receive side of the USIC while letting the transmit side run?
Thanks.

Hi jscott27,
When you fixed DX0 to 1, basically you already turn it off as there is no data transaction anymore.
May I know why to fixed it at 1 is not suitable for your application?
