Notes:
39. X1 is the Almost Empty offset for FIFO used by AE. Y is the Almost Full offset for FIFO used by AF. Both X1 and Y1 are selected during a FIFO reset or port
A programming.
40. When a word loaded to an empty FIFO is shifted to the output register, its previous FIFO memory location is free.
41. Data in the output register does not count as a
“
word in FIFO memory
”
. Since in FWFT Mode, the first word written to an empty FIFO goes unrequested to
the output register (no read operation necessary), it is not included in the FIFO memory count.
42. The OR and IR functions are active during FWFT mode; the EF and FFA functions are active in CY Standard Mode.
43. BE is selected at Master Reset; BM and SIZE must be static throughout device operation.
