22.5.2.53 Receive FIFO Watermark and Selection Register (RFWMSR)
This register is used to
•
select a receiver FIFO for subsequent programming access through the receiver FIFO
configuration registers summarized in
•
to define the watermark for the selected FIFO.
22.5.2.54 Receive FIFO Start Index Register (RFSIR)
This register defines the message buffer header index of the first message buffer of the selected FIFO.
