NOTES:
1. During the output selection of two Queues, partial reset of the two Queues involved are prohibited.
2. During partial reset the high-impedance control of the output is provided by OE only.
3. PRS0/1 must go LOW after the fourth rising edge of RCLK0.
4. This is the output data from Queue0 and Queue1.
