Figure 3. Parallel Programming of the Almost-Full Flag and Almost-Empty Flag Offset Values after Reset (IDT Standard and FWFT Modes)
NOTES:
1. FIFO2 is reset in the same manner to load X2 and Y2 with a preset value.
2. If FWFT is HIGH, then EFB/ORB will go LOW one CLKB cycle earlier than in this case where FWFT is LOW.
NOTES:
1. t
2. CSA = LOW, W/RA = HIGH, MBA = LOW. It is not necessary to program offset register on consecutive clock cycles.
