SI914OCY SI914OCY SI914OCY on stock Notes: 22. "Count" is the number of words in the FIFO. 23. The FIFO is assumed to be_programmed with P>O (i.e., PAFE does not transition at Empty or Full). 24. R2 is ignored because the FIFO is empty (count = 0). It is important to note that R3 is also ignored because W3, the first enabled write after empty, occurs less than tSKEW2 before R3. Therefore, the FIFO still appears empty when R3 0ccurs. Because W3 0ccurs greater than tSKEW2 before R4, R4 includes W3 in the flag update. 25. CKR is clock; CKW is opposite clock. 26. R3 updates the flag to the Empty state by asserting E/F. Because Wl occurs greater than tSKEWi after R3, R3 does not recognize Wl when updating flag status. But because Wl occurs greater than tSKEW2 before R4, R4 includes Wl in the flag update and, therefore, updates FIFO to Almost Empty state. It is important to note that R4 is a latent cycle; i.e., it only updates the flag status regardless of the state of ENR. It does not change the count or the FIFO's data outputs.
