Full Flag Timing
Programmable Almost Empty Flag Timing
Notes:
22.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
SKEW2
, then PAE may not change state until the next RCLK.
23.PAE offset = n.
24.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.
