TxFIL – Transmitter FIFO Interrupt Level A and B
The position in the Tx FIFO that caused the transmitter will enter the interrupt arbitration process. This register is used to offset the effect of the
arbitration threshold. It use may yield moderate improvements in the interrupt service. It will also ‘equalize’ interrupt latency and allow for larger
aggregate block transfers between fast and slow channels. Writing to this register removes the interrupt control established in MR0 and MR1.
TxEL – Transmitter FIFO Empty Level Register
The number of empty bytes in the Transmitter FIFO.
Registers for Character Recognition
Please not 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.
XonCR – Xon/Xoff Character Register A and B
An 8-bit character register that contains the compare value for a Xon character.
XoffCR – Xoff Character Register A and B
An 8-bit character register that contains the compare value for a Xoff character.
ARCR – Address Recognition Character Register A and B
An 8 bit character register that contains the compare value for the wake-up address character.
