NOTE: The TUSB3410 does support baud rates lower than 1200 bps, which are not

listed due to less interest.

7.1.12 XON: Xon Register (Addr:FFA9)

This register contains a value that is compared to the received data stream. Detection of a match interrupts the MCU

(only if the interrupt enable bit is set). This value is also used for Xon transmission.

7.1.13 XOFF: Xoff Register (Addr:FFAA)

This register contains a value that is compared to the received data stream. Detection of a match halts the DMA

transfer, and interrupts the MCU (only if the interrupt enable bit is set). This value is also used for Xoff transmission.
