NOTES:
1.
Pulse widths less than the stated minimum values may cause incorrect operation.
2.
Values are guaranteed by design; not currently tested.
3.
These times also apply to the Programmable-Almost-Full and Half-Full flags when they are synchronized to WCLK.
4.
These times also apply to the Half-Full and Programmable-Almost-Empty flags when they are synchronized to RCLK.
