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