Programmable Almost–Full Flag
(
PAFA
,
PAFB
)
—
PAFA
(
PAFB
) will go
LOW when the amount of data in Array A (B) reaches the almost-full condition.
If no reads are performed after Reset,
PAFA
(
PAFB
) will go LOW after (256-m
writes to the IDT72801's FIFO A (B); (512-m writes to the IDT72811's FIFO
A (B); (1,024-m writes to the IDT72821's FIFO A (B); (2,048-m writes to the
IDT72831's FIFO A (B); (4,096-m writes to the IDT72841's FIFO A (B); or
(8,192-m writes to the IDT72851's FIFO A (B).
FFA
(
FFB
) is synchronized with respect to the LOW-to-HIGH transition of the
Write Clock WCLKA (WCLKB). The offset “m” is defined in the Full Offset
registers.
If there is no Full offset specified,
PAFA
(
PAFB
) will go LOW at Full-7 words.
PAFA
(
PAFB
) is synchronized with respect to the LOW-to-HIGH transition
of WCLKA (WCLKB).
Programmable Almost–Empty Flag
(
PAEA
,
PAEB
)
—
PAEA
(
PAEB
) will
go LOW when the read pointer is "n+1" locations less than the write pointer. The
offset "n" is defined in the Empty Offset registers. If no reads are performed after
Reset,
PAEA
(
PAEB
) will go HIGH after "n+1" writes to FIFO A (B).
If there is no Empty offset specified,
PAEA
(
PAEB
) will go LOW at Empty+7
words.
PAEA
(
PAEB
) is synchronized with respect to the LOW-to-HIGH transition
of the Read Clock RCLKA (RCLKB).
