NOTES:
1. n = PAE offset.
2. For IDT Standard mode
3. For FWFT mode.
4. t
5. PAE is asserted and updated on the rising edge of WCLK only.
NOTES:
1. For IDT Standard mode: D = maximum FIFO depth. D = 8,192 for the IDT72V255LA and 16,384 for the IDT72V265LA.
2. For FWFT mode: D = maximum FIFO depth. D = 8,193 for the IDT72V255LA and 16,385 for the IDT72V265LA.
