Receive Signaling Status Register 3 (Read)
Value after reset: 00
RSIS3
RSIS3 relates to the last received HDLC channel 3 frame; it is copied into RFIFO3 when
end-of-frame is recognized (last byte of each stored frame).

Valid Frame - HDLC Channel 3
Determines whether a valid frame has been received.
1
0
An invalid frame is either
– a frame which is not an integer number of 8 bits (n 8 bits) in length
– a frame which is too short taking into account the operation mode
Note: Shorter frames are not reported.
Receive Data Overflow - HDLC Channel 3
A data overflow has occurred during reception of the frame.
Additionally, an interrupt can be generated
(refer to ISR5.RDO3/IMR5.RDO3).
CRC16 Compare/Check - HDLC Channel 3
0
1
Receive Message Aborted - HDLC Channel 3
This bit is set, if more than 5 contiguous 1-bits are detected.
RDO3
H
(e.g. 25 bits), or
selected via MODE3 (MDS3(2:0)) and the selection of receive CRC
ON/OFF (CCR4.RCRC3) as follows:
• MDS3(2:0)=011 (16 bit Address),
• MDS3(2:0)=010 (8 bit Address),
RCRC3=0: 4 bytes; RCRC3=1: 3 or 4 bytes
RCRC3=0: 3 bytes; RCRC3=1: 2 or 3 bytes
CRC check failed; received frame contains errors.
CRC check o.k.; received frame is error-free.
