When
FF
BA
is LOW, the B
→
A FIFO is full and further data writes into Port B are inhibited.
When
FF
BA
is HIGH, the FIFO is not full.
FF
BA
is synchronized to CLK
B
. In bypass mode,
FF
BA
tells Port B that a message is waiting in Port A’s output register. If
FF
BA
is LOW, a
bypass message is in the register. If
FF
BA
is HIGH, Port A has read the message and another
message can be written into Port B.
This flag informs Port B that the Synchronous BiFIFO is in bypass mode. When BYP
B
is
LOW, Port A has placed the FIFO into bypass mode. If
BYP
B
is HIGH, the Synchronous
BiFIFO passes data into memory.
BYP
B
is synchronized to CLK
B
.
A LOW on this pin will perform a reset of all Synchronous BiFIFO functions.
There are three +5V power pins for the PLCC and PGA packages and two for the TQFP.
There are seven ground pins for the PLCC and PGA packages and four for the TQFP.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
