3. tSKEW2 is the minimum time between a rising RCLKA (RCLKB) edge and a rising WCLKA (WCLKB) edge for
PAFA (PAFB) to change during that clock cycle. If the time between the
rising edge of RCLKA (RCLKB) and the rising edge of WCLKA (WCLKB) is less than tSKEW2, then
PAFA (PAFB) may not change state until the next WCLKA (WCLKB) rising edge.
4. If a write is performed on this rising edge of the write clock, there will be Full - (m-1) words in FIFO A (B) when
PAFA (PAFB) goes LOW.

tSKEW2 is the minimum time between a rising WCLKA (WCLKB) edge and a rising RCLKA (RCLKB) edge for
PAEA (PAEB) to change during that clock cycle. If the time between the
rising edge of WCLKA (WCLKB) and the rising edge of RCLKA (RCLKB) is less than tSKEW2, then
PAEA (PAEB) may not change state until the next RCLKA (RCLKB) rising edge.
3.
If a read is performed on this rising edge of the read clock, there will be Empty + (n-1) words in FIFO A (B) when
PAEA (PAEB) goes LOW.
