abort<br />
reserved2<br />
SYNC Holds the synchronization pattern<br />
<strong>for</strong> the receive machine and<br />
opening/closing flag/sync-pattern<br />
<strong>for</strong> the transmit machine.<br />
The abort pattern is transmitted<br />
upon receiving an abort command.<br />
This is an HDLC flag so no additional<br />
programing is needed <strong>for</strong> the<br />
HDLC protocol. After reset it holds<br />
the value of 7E in the SYNC field<br />
ENTER_HUNT EH Upon receiving the Enter Hunt<br />
command, the receive machine<br />
moves to HUNT state and continuously<br />
searches <strong>for</strong> an opening flag.<br />
If the enter hunt mode command is<br />
issued during frame reception, the<br />
current descriptor is closed with<br />
CRC error 1. The EH bit is cleared<br />
upon entering Hunt state.<br />
