Notes:
19. PAE offset – n. Number of data words into FIFO already = n.
20. PAE offset – n.
21. t
is the minimum time between a rising WCLK and a rising RCLK edge for PAE to change state during that clock cycle. If the time between the edge of WCLK and the
rising RCLK is less than t
, then PAE may not change state until the next RCLK.
22. If a read is performed on this rising edge of the read clock, there will be Empty + (n – 1) words in the FIFO when PAE goes LOW.
