The time-guard feature enables the UART interface to operate with slow remote devices.
When set, it will insert a number of idle states between transmitting two characters, the length of which can be set in the UART_TIMEGUARD register. The value in the register defines the number of baud clocks of idle period to insert.
This idle state essentially acts like a long stop bit.
