Since the serial link characteristics are based on how the control registers are programmed, the PRU_ICSSG UART0 module will expect the control registers to be static while it is busy engaging in a serial communication. Therefore, changing the control registers while the module is still busy communicating with another serial device will most likely cause an error condition and should be avoided.
