STATISTIC_ACTION[0:3] Bit Descriptions
Description
Reserved.
Pre Divider. Used if ALWAYS_DEC (bit 4) is set. The predivider is free running and
extends the depth of the counter.
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.
Assert AERR on cnt = 0. Assert AERR when STATISTIC_CNT[x] reaches 0.
0: Disable.
1: Enable.
Assert ASMI on cnt = 0. Assert ASMI when STATISTIC_CNT[x] reaches 0.
0: Disable.
1: Enable.
Always Decrement Counter. If enabled, the counter decrements on every memory
clock subject to the prescaler value PREDIV (bits [23:8]). Decrementing continues unless
loading is occurring due to another action, or if the counter reaches zero and WRAP is
disabled (bit 7).
0: Disable.
1: Enable
Assert AERR on Descirptor Hit. The descriptor hits are ANDed with the masks and
then all ORed together.
0: Disable.
1: Enable
