*
* Summary:
* Changes the HSIOM settings for the UART output pins (TX and/or RTS) to keep
* them inactive after the block is disabled. The output pins are controlled by
* the GPIO data register. Also, the function disables the skip start feature to
* not cause it to trigger after the component is enabled.
*
* Parameters:
* None
*
* Return:
* None
