Hide
If in SysConfig, the UART module data direction is set for send only, the code will crash in UART_open(). It crashes in GPIOPinConfiguration() because it is writing to bad address.

Looking at UARTMSP432E4_open(), I see it configuring both TX and RX pins, even though I indicated data direction is send only.

Workaround is to open the UART for both Rx and Tx.
