8.1 Start-up Sequence

When first powering up the device, five pulses are required on CLK-SCL for the reading of internal registers. This can be accomplished by sending one full command byte to the device. The device will not respond, but it will then be ready to respond to the next correct command sequence.

Power up V_CC.
An external pull-up resistor pulls I/O-SDA high with V_CC.
After stable V_CC, five pulses are applied to CLK-SCL.
CLK-SCL and I/O-SDA may then be driven.
