VEEG

External clock inputs.

When ECLKSEL∗ is

set to low level, the

clock input to these

pins is used as the

transmission bit

clock. EXCLK is

biased to become

low level when left

open.

Serial data inputs.

When SDSEL is set

to high level, the data

input to these pins is

output unmodified

from SDOUT.
