Table 4-22
Data input bus.
Data input parity bus. Not used when standard mode is used.
Write enable. When WREN = 1, data will be written into memory. When WREN = 0,
write is disabled
Read enable. When RDEN = 1, data will be read from memory. When RDEN = 0, read
is disabled.
Asynchronous reset of FIFO counter and flags. Reset must be asserted for three clock
cycles. Reset does not affect DO or ECC signals.
Clock for write operations.
Clock for read operations.
Data output bus.
Data output parity bus.
Single-bit error status.
Double-bit error status.
ECC encoder output bus.
FIFO FULL flag.
FIFO ALMOSTFULL flag.
FIFO EMPTY flag.
The FIFO data read pointer.
The FIFO data write pointer.
When the FIFO is full, any additional write operation generates an error flag.
When the FIFO is empty, any additional read operation generates an error flag.
FIFO ALMOSTEMPTY flag.
