PREDIV

Pre-divider used for ALWAYS_DEC. The pre-divider is free running and extends the

depth of the counter.

7WRAP

Decrement Counter Beyond Zero and Wrap.

0: Disable wrap; counter stops when it reaches zero.

1: Enable wrap; counter decrements through 0 to all ones.

ZERO_ERR

Asset AERR on Cnt = 0. Assert AERR (internal GLIU_P_SERR) when

STATISTIC_CNT[x] = 0.

0: Disable.

1: Enable.

ZERO_SMI

Assert ASMI on Cnt = 0. Assert ASMI (internal GLIU_P_ASMI) when

STATISTIC_CNT[x] = 0.

0: Disable.

1: Enable.

ALWAYS_DEC

Always Decrement Counter. If enabled, the counter will decrement on every memory

clock, subject to the prescaler value PREDIV (bits [23:8]). Decrementing will continue

unless loading is occurring due to another action, or if the counter reaches zero and

WRAP is disabled (bit[7]).

0: Disable.

1: Enable.
