Bits 7 to 0: Leaky Bucket 0 Upper Threshold (LB0U[7:0]). When the leaky bucket accumulator is equal to the
value stored in this field, the activity monitor declares an activity alarm by setting the input clock’s ACT bit in the
appropriate ISR register. Registers LB0U, LB0L, LB0S, and LB0D together specify leaky bucket configuration 0.
See Section 7.5.2.

Bits 7 to 0: Leaky Bucket 0 Lower Threshold (LB0L[7:0]). When the leaky bucket accumulator is equal to the
value stored in this field, the activity monitoring logic clears the activity alarm (if previously declared) by clearing the
input clock’s ACT bit in the appropriate ISR register. Registers LB0U, LB0L, LB0S, and LB0D together specify
leaky bucket configuration 0. See Section 7.5.2.

Bits 7 to 0: Leaky Bucket 0 Size (LB0S[7:0]). This field specifies the maximum value of the leaky bucket. The
accumulator cannot increment past this value. Registers LB0U, LB0L, LB0S, and LB0D together specify leaky
bucket configuration 0. See Section 7.5.2.

Bits 1 and 0: Leaky Bucket 0 Decay Rate (LB0D[1:0]). This field specifies the decay or “leak” rate of the leaky
bucket accumulator. For each period of 1, 2, 4, or 8 128ms intervals in which no irregularities are detected on the
input clock, the accumulator decrements by 1. Registers LB0U, LB0L, LB0S, and LB0D together specify leaky
bucket configuration 0. See Section 7.5.2.
00 = decrement every 128ms (8 units/second)
01 = decrement every 256ms (4 units/second)
10 = decrement every 512ms (2 units/second)
11 = decrement every 1024ms (1 unit/second)
