I/O Timing

Digital Output

By default, the ASX340AT launches pixel data, FV, and

LV synchronously with the falling edge of PIXCLK. The

expectation is that the user captures data, FV, and LV using

the rising edge of PIXCLK. The timing diagram is shown in.

As an option, the polarity of the PIXCLK can be inverted

from the default by programming R0x0016[14].
