NOTES:
1. If the write port is configured in double data rate, partial reset must be initiated after the falling edge of WCLK0 to ensure falling edge data is written into memory.
2. Only the read enable of the Queue involved in partial reset need to be HIGH.
3. During partial reset the high-impedance control of the outputs is provided by OE only.
4. Only affects the output of the Queue partial reset is applied to.
