All timing specifications except those are referenced to the rising
edge of CLK.
Input Parameter Write Clock.
The internal image transformation
and configuration control parameter registers are double buffered
to simplify interfacing with system controllers. Depending on the
state of the chip selects ICS, control words input to IDAT
the corresponding addresses presented to IADR
into the outer preload registers on the rising edge of the Input
parameter Write clock IWR. The last parameter must be loaded
twice on two consecutive rising edges of IWR.
