Input control pin using S2Cwire serial interface. The device
records rising edges of the clock and decodes them into 32
(AAT4296) or 64 (AAT4298) states controlling the ON/OFF
states of the outputs. See Table 1 for output settings. In addi-
tion, a logic low forces the device into shutdown mode, reduc-
ing the supply current to less than 1µA. This pin should not be
left floating.
