HCSV Registers
Reading a channel from the Receive Output Buffer and Writing to a channel in the
Transmit Input Buffer is done according to the channel’s status vector in the Transmit
Output Buffer. This vector contains 7 flags:

Normal operation
The last bits of a message have not filled an octet (8 bits)
No CRC error in received message
CRC error was detected in the received message
Normal operation
HDLCU has detected an end of message flag in the receive
direction. The DSP must read the octet in the Receive Output
Buffer before the next message start flag is detected
Normal operation
The DSP has detected an incoming abort message (7
consecutive ’1s’). The STOP flag is also set to 1. This means
that the DSP should ignore the current message being
transmitted over the channel in question and report to the
external micro controller
