Transmit Data Link Message Transmitted Interrupt Enable—Set to enable interrupt assertion
on INTR* pin due to end of transmission of a full message, see
Transmit Data Link FIFO Underrun Interrupt Enable—Set to enable interrupt assertion on
INTR* pin due to Data Link FIFO underrun error, see
Transmit Data Link FIFO Near-Empty Interrupt Enable—Set to enable interrupt assertion on
INTR* pin due to the FIFO buffer being near empty, see
Transmit Data Link FCS Calculation Enable—Set to enable FCS calculation over the
transmitted message and add it to the end of the transmitted message. When cleared, the FCS
calculation and addition are executed by the software.
Transmit Data Link FIFO Near Empty Threshold—Set to the threshold value, used to indicate
a near-empty FIFO event. The range of values available for this purpose is 0–126, where 00(h)
is interpreted as 0, 01(h) is 1 …etc. and 7E(h) is interpreted as 126.
