I'm trying to implement send && recieve through one wire. Handling of pin state, if it is input or output is done via SW. Also it is going to be half-duplex only.
Is it possible to do something like this:
NRF_UART0->PSELTXD=PIN_TX_RX;
NRF_UART0->PSELRXD=PIN_TX_RX;
After some experimentation I was unable to get it to run.
