CPU Address EC0
Accessed by CPU (R/W)
If CPU wants to reset pools again, CPU has to clear bit 5 and then set bit 5.
Note : Before CPU doing so, CPU should set QCTRL (CPU Address EBA) bit 2 and bit 3 to one. After reset the
pools, CPU shall reprogram free granule link list (CPU address EC1, EC2, EC3, EC4, EC5, EC6). Then clear
QCTRL (EBA).
