DESCRIPTION

Energy Detect Bust Disable:

Disable bursting of energy detect data pulses. By default, Energy

ED_BURST_DIS

0, RW

Detect (ED) transmits a burst of 4 ED data pulses each time the CD is

powered up. When bursting is disabled, only a single ED data pulse

will be send each time the CD is powered up.

Energy Detect Power State:

Indicates current Energy Detect Power state. When set, Energy

ED_PWR_STATE

0, RO

Detect is in the powered up state. When cleared, Energy Detect is in

the powered down state. This bit is invalid when Energy Detect is not

enabled.

Energy Detect Error Threshold Met:

ED_ERR_MET

0, RO/COR

No action is automatically taken upon receipt of error events. This bit

is informational only and would be cleared on a read.

Energy Detect Data Threshold Met:

ED_DATA_MET

0, RO/COR

The number of data events that occurred met or surpassed the

Energy Detect Data Threshold. This bit is cleared on a read.

Energy Detect Error Threshold:

Threshold to determine the number of energy detect error events that

7:4

ED_ERR_COUNT

0001, RW

should cause the device to take action. Intended to allow averaging of

noise that may be on the line. Counter will reset after approximately 2

seconds without any energy detect data events.

Energy Detect Data Threshold:

Threshold to determine the number of energy detect events that

3:0

ED_DATA_COUNT

0001, RW

should cause the device to take actions. Intended to allow averaging

of noise that may be on the line. Counter will reset after approximately

2 seconds without any energy detect data events.
