Not Assigned. Should be set to zero when written.
Receive HDLC Reset. A 0-to-1 transition will reset the HDLC controller.
Must be cleared and set again for a subsequent reset.
Transmit Flag/Idle Select.
0 = 7Eh
1 = FFh
Transmit HDLC Reset. A 0-to-1 transition will reset the HDLC
controller. Must be cleared and set again for a subsequent reset.
Transmit Abort. A 0-to-1 transition will cause the FIFO contents to be
dumped and one FEh abort to be sent followed by 7Eh or FFh flags/idle
until a new packet is initiated by writing new data into the FIFO. Must be
cleared and set again for a subsequent abort to be sent.
Transmit End of Message. Should be set to a one just before the last data
byte of a HDLC packet is written into the transmit FIFO at THFR. This bit
will be cleared by the HDLC controller when the last byte has been
transmitted.
Transmit Zero Stuffer Defeat. Overrides internal enable.
0 = enable the zero stuffer (normal operation)
1 = disable the zero stuffer
Transmit CRC Defeat.
0 = enable CRC generation (normal operation)
1 = disable CRC generation
