Leaky bucket alarm assert threshold, 1 ~ 63
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.
Invalid values will not be written to the register.
Default value: 15

Leaky bucket alarm de-assert threshold, 0 ~ 62
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. Invalid values will not be written to the register.
