Receive Packet End. Set when the HDLC controller detects either the finish of a valid
message (i.e., CRC check complete) or when the controller has experienced a message
fault such as a CRC checking error, or an overrun condition, or an abort has been seen.
The setting of this bit prompts the user to read the RPRM register for details.
Receive Packet Start. Set when the HDLC controller detects an opening byte. The
setting of this bit prompts the user to read the RPRM register for details.
Receive FIFO Half Full. Set when the receive 64–byte FIFO fills beyond the half way
point. The setting of this bit prompts the user to read the RPRM register for details.
Receive FIFO Not Empty. Set when the receive 64–byte FIFO has at least one byte
available for a read. The setting of this bit prompts the user to read the RPRM register
for details.
Transmit FIFO Half Empty. Set when the transmit 64–byte FIFO empties beyond the
half way point. The setting of this bit prompts the user to read the TPRM register for
details.
Transmit FIFO Not Full. Set when the transmit 64–byte FIFO has at least one byte
available. The setting of this bit prompts the user to read the TPRM register for details.
Transmit Message End. Set when the transmit HDLC controller has finished sending a
message. The setting of this bit prompts the user to read the TPRM register for details.
