Data Inputs for 9-bit bus.
The only write enable when device is configured to have programmable flags. Data
is written on a LOW-to-HIGH transition of WCLK when WEN is asserted and FF is HIGH.
Enables the device for Read operation. REN must be asserted LOW to allow a Read
operation.
The rising edge clocks data into the FIFO when WEN is LOW and the FIFO is not Full.
When LD is asserted, WCLK writes data into the programmable flag-offset register.
The rising edge clocks data out of the FIFO when REN is LOW and the FIFO is not
Empty. When LD is LOW, RCLK reads data out of the programmable flag-offset register.
