Reserved. Unknown During Read.
Digital PLL Error. (Read Only)
1 - A frame receive was aborted because the DPLL lost
synchronization with the carrier.
0 - DPLL has not lost carrier during frame reception.
This bit is only valid when set up to receive Manchester-
encoded synchronous HDLC.
Digital PLL Carrier Sense. (Read Only)
1 - DPLL tacked onto a carrier.
0 - DPLL does not sense a carrier.
Link Idle. (Read Only)
0 - RX data signal has changed within two bit periods
1 - RX data signal has not changed within two bit periods.
This bit is only valid when set up to receive Manchester-
encoded synchronous HDLC.
CRC Error. (Read Only)
0 - No CRC check errors encountered in incoming frame.
1 - CRC calculated on the incoming data does not match
CRC value contained within the received frame. This bit is
set with the last data in the incoming frame along with
EOF.
Receive FIFO Overrun. (Read Only)
0 - RX FIFO has not overrun.
1 - RX logic attempted to place data in the RX FIFO while
it was full. The most recently read data is the last valid
data before the overrun. The rest of the incoming frame is
dropped. EOF is also set.
