words for the IDT72851.
3. t
SKEW2
is the mnimumtime 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 t
SKEW2
, 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.

t
SKEW2
is the mnimumtime 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 t
SKEW2
, then
PAEA
(

) may not change state until the next RCLKA (RCLKB) rising edge.
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

) goes LOW.
