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

VFR
Valid Frame
Determines whether a valid frame has been received.
An invalid frame is either
– 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 RFIFO data overflow has occurred during reception of the frame.
Additionally,
ISR1.RDO/IMR1.RDO).
CRC16 Compare/Check
Receive Message Aborted
The received frame was aborted from the transmitting station.
According to the HDLC protocol, this frame must be discarded by the
receiver station.
1… valid
0… invalid
0… CRC check failed; received frame contains errors.
1… CRC check o.k.; received frame is error-free.
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
