BOM…
Receive Signaling Status Register (Read)
RSIS relates to the last received HDLC or BOM frame; it is copied into RFIFO when end-
of-frame is recognized (last byte of each stored frame).

Valid Frame
Determines whether a valid frame has been received.
– a frame which is not an integer number of 8 bits (n
– a frame which is too short taking into account the operation mode
Note:Shorter frames are not reported.
Receive Data Overflow
A data overflow has occurred during reception of the frame.
Additionally, an interrupt can be generated
(refer to ISR1.RDO/IMR1.RDO).

An invalid frame is either
RDO
(e.g. 25 bits), or
selected via MODE (MDS2...0) and the selection of receive CRC
ON/OFF (CCR3.RCRC) as follows:
• MDS2...0 = 011 (16 bit Address),
• MDS2...0 = 010 (8 bit Address),
RCRC = 0 : 4 bytes; RCRC = 1 : 3-4 bytes
RCRC = 0 : 3 bytes; RCRC = 1 : 2-3 bytes
