ADDR[3:0]
LVTTL input
asynchronous,
internal pull-up
Control Addressing Bus
. The ADDR[3:0] bus is the input address bus used to
configure the device. The WREN input writes the values of the DATA[7:0] bus into the
latch specified by the address location on the ADDR[3:0] bus.

Table 9
lists the
configuration latches within the device, and the initialization value of the latches upon
the assertion of RESET.
Table 10
shows how the latches are mapped in the device.
DATA[7:0]
LVTTL input
asynchronous,
internal pull-up
Control Data Bus
. The DATA[7:0] bus is the input data bus used to configure the
device. The WREN input writes the values of the DATA[7:0] bus into the latch
specified by address location on the ADDR[3:0] bus.
