This register contains data read from the channel provision RAM after an indirect
read operation or data to be inserted into the channel provision RAM in an
indirect write operation.
XFER[3:0]:
The indirect channel transfer size (XFER[3:0]) configures the amount of data
transferred in each transaction. The channel transfer size to be written to the
channel provision RAM, in an indirect write operation, must be set up in this
register before triggering the write. When the channel FIFO depth reaches
the depth specified by XFER[3:0] or when an end-of-packet exists in the
FIFO, a poll of this FREEDM-84A672 device will indicate that data exists and
is ready to be transferred across the receive APPI. Channel transfer size is
measured in 16 byte blocks. The amount of data transferred and the depth
threshold are specified by given setting is:
