Synchronous Clock for SETS

Data sheet

Preliminary

Default value: m = 0, (1ms)

Leak_Obs_Window, 0x08 (R/W)

Sets the leak observation window size for the reference activity monitor to (n + 1) times the fill observation win-

dow size. The size can be set from 1 to 16ms times the fill observation window size.

Default value: n = 3, (4 times)

Bucket_Size, 0x09 (R/W)

Sets the leaky bucket size for the reference activity monitor. Bucket size equal to 0 will bypass the leaky bucket

accumulator, and assert or de-assert the activity alarm based on results of frequency detector and pulse moni-

tor only. The bucket size must be greater than or equal to the alarm assert value. Otherwise, the value will not

be written to the register.

Default value: 20

Assert_Threshold, 0x0A (R/W)

Sets the leaky bucket alarm assert threshold for the reference activity monitor. The alarm assert threshold

value must be greater than the de-assert threshold value and less than or equal to the bucket size value. Oth-

erwise, the value will not be written to the register.

Default value: 15

De_Assert_Threshold, 0x0B (R/W)

Sets the leaky bucket alarm de-assert threshold for the reference activity monitor. The de-assert threshold

value must be less than the assert threshold value. Otherwise, the value will not be written to the register.

Default value: 10
