NOTES:
1. For a Partial Reset to be performed on a Queue, that Queue must be selected on both the write and read ports.
2. The queue must be selected a minimum of 2 clock cycles before the Partial Reset takes place, on both the write and read ports.
3. The Partial Reset must be LOW for a minimum of 1 WCLK and 1 RCLK cycle.
4. Writing or Reading to the queue (or a queue change) cannot occur until a minimum of 3 clock cycles after the Partial Reset has gone HIGH, on both the write and read ports.
5. The PAF flag output for Qx on the PAFn flag bus may update one cycle later than the active PAF flag.
6. The PAE flag output for Qx on the PAEn flag bus may update one cycle later than the active PAE flag.
