SPI/I2C UART with 128-Word FIFOs
Bits 7–4: RxTrig[3:0]
These 4 bits allow definition of the receive FIFO threshold level at which an ISR[3] interrupt is generated. This can be
used to signal that the receive FIFO is nearing overflow or that a predefined number of FIFO locations are available for
being read out in one block.
The actual FIFO trigger level is 8 times RxTrig[7:4], hence, the selectable threshold granularity is eight.
Bits 3–0: TxTrig[3:0]
These 4 bits allow definition of the transmit FIFO threshold level at which the MAX3107 generates an ISR[4] interrupt.
This can be used to manage data flow to the transmit FIFO. For example, if the trigger level is defined near the bottom
of the TxFIFO, the host knows that a predefined number of FIFO locations are available for being written to in one block.
Alternatively, if the trigger level is set near the top of the FIFO, the host is warned when the transmit FIFO is nearing
overflow, if written to on a word-by-word basis.
The actual FIFO trigger level is 8 times TxTrig[3:0], hence, the selectable threshold granularity is eight.
Bits 7–0: TxFL[7:0]
The TxFIFOLvl register represents the current number of words in the transmit FIFO.
Bits 7–0: RxFL[7:0]
The RxFIFOLvl register represents the current number of words in the receive FIFO.
