Received Good Block Indication—Defines the type of status byte. Set for status with length
type in it (a good block [a1] or [a2] blocks). Cleared for status byte with error type in it (a bad
block [b]).
Receive Data Link Overrun Error—Set when the receive FIFO is full and another byte was
received from the line and should be written into the FIFO (and it is not already set). Cleared if
it was set and there are no more unread complete blocks left in the FIFO (this is determined by
RxBlk bit in this register).
Receive Data Link FIFO Contains a Message—Set when another status byte of a correct-end-
of-message or an incorrect-end-of-message (including aborted message) is written into the
FIFO. Cleared when this register is read.
Receive Data Link Near-Full Event—Set when the number of bytes in the receive FIFO equals
or exceeds the programmable threshold written in RxNFThr register (and it is not already set).
Cleared if was set and there are no more unread complete blocks left in the FIFO (this is
determined by RxBlk bit in this register).
Receive Data Link FIFO Contains Complete Blocks—Set when there is one or more complete
data blocks in the receive FIFO. Cleared when the last data byte of the last complete block is
read from the FIFO.
Byte Type Indication—Set when the next byte to be read from the receive FIFO is a status byte.
Clear when the next byte to be read is a data byte. When RxBlk bit in this register is clear, this
bit is undefined, i.e., there is no complete block in the FIFO.
