WCLK0
NOTES:
1. The timing diagram shown is for FIFO0. FIFO1-3 exhibit the same behavior.
2. m0 = PAF0 offset.
3. D = maximum FIFO depth. For density of FIFO with bus-matching, refer to the bus-matching section on page 19.
4. PAF0 is asserted to LOW on WCLK0 transition and reset to HIGH on RCLK0 transition.
5. RCS0 = LOW, and WCS0 = LOW.
6.
WCLK0
NOTES:
1. The timing diagram shown is for FIFO0. FIFO1-3 exhibit the same behavior.
2. n0 = PAE0 offset.
3. For IDT Standard Mode.
4. For FWFT Mode.
5. PAE0 is asserted LOW on RCLK0 transition and reset to HIGH on WCLK0 transition.
6. RCS0 = LOW, and WCS0 = LOW.
