ERCLK0
NOTES:
1. The EREN0 output is “or gated” to RCS0 and REN0 and will follow these inputs provided that the Queue is not empty. If the Queue is empty, EREN0 will go HIGH to indicate that
2. The EREN0 output is synchronous to RCLK0.
3. OE0 = LOW, WDDR = HIGH, and RDDR = HIGH.
4. Q[39:10] = 0.
5. The truth table for EREN is shown below:
