NOTES:
1. FIFO2 Master Reset (MRS2) is performed in the same manner to load X2 and Y2 with a preset value. For FIFO2 Master Reset, MRS1 must toggle simultaneously with MRS2.
2. PRS1 must be HIGH during Master Reset.
3. If BE/FWFT is HIGH, then EFB/ORB will go LOW one CLKB cycle earlier than in this case where BE/FWFT is LOW.

NOTES:
1. Partial Reset is performed in the same manner for FIFO2.
2. MRS1 must be HIGH during Partial Reset.
3. If BE/FWFT is HIGH, then EFB/ORB will go LOW one CLKB cycle earlier than in this case where BE/FWFT is LOW.
