UPPER_THRESHOLD_3_CNFG - Upper Threshold for Leaky Bucket Configuration 3
LOWER_THRESHOLD_3_CNFG - Lower Threshold for Leaky Bucket Configuration 3
BUCKET_SIZE_3_CNFG - Bucket Size for Leaky Bucket Configuration 3
Address: 3DH
Type: Read / Write

7 - 0
UPPER_THRESHOLD_3_DATA[7:0]
These bits set an upper threshold for the internal leaky bucket accumulator. When the number of the accumu-
lated events is above this threshold, a no-activity alarm is raised.
Address: 3EH
Type: Read / Write
Default Value: 00000100

LOWER_THRESHOLD_3_DATA[7:0]
These bits set a lower threshold for the internal leaky bucket accumulator. When the number of the accumu-
lated events is below this threshold, the no-activity alarm is cleared.
Address: 3FH
Type: Read / Write
Default Value: 00001000

Description
7 - 0
BUCKET_SIZE_3_DATA[7:0]
These bits set a bucket size for the internal leaky bucket accumulator. If the number of the accumulated events reach
the bucket size, the accumulator will stop increasing even if further events are detected.
