Data inputs for 9-bit bus.
Data outputs for 9-bit bus.
The only write enable to have programmable flags when device is configured. Data is
written on a LOW-to-HIGH transition of WCLK when WEN1 is asserted and FF is HIGH.
If the FIFO is configured to have two write enables, data is written on a LOW-to-HIGH
transition of WCLK when WEN1 is LOW and WEN2/LD and FF are HIGH.
If HIGH at reset, this pin operates as a second write enable. If LOW at reset, this pin
operates as a control to write or read the programmable flag offsets. WEN1 must be
LOW and WEN2 must be HIGH to write data into the FIFO. Data is not written into the
FIFO if the FF is LOW. If the FIFO is configured to have programmable flags, WEN2/LD
is held LOW to write or read the programmable flag offsets.
Enables device for read operation.
The rising edge clocks data into the FIFO when WEN1 is LOW, WEN2/LD is HIGH, and
the FIFO is not Full. When LD is asserted, WCLK writes data into the programmable
flag-offset register.
