3.3 V, 5 V UART, 3.125 Mbit/s, with 256-byte FIFO

8.3 Registers for character recognition

Please note that, although the names of the registers imply a particular function, there is

not any hardware function directly attached to them. They are just three characters that

may be used for any function requiring recognition or simple character stripping.

It is only when other internal logic is enabled that the reception of a recognized character

will trigger particular chip functions and/or interrupts.

8.3.1 Xon Character Register (XonCR)

An 8-bit character register that contains the compare value for an Xon character.

8.3.2 Xoff Character Register (XoffCR)

An 8-bit character register that contains the compare value for an Xoff character.

8.3.3 Address Recognition Character Register (ARCR)

An 8-bit character register that contains the compare value for the wake-up address

character.
