Power-Up Sequence

Power is supplied from the host to the sensor. After power is supplied, the following sequence is

performed:

 The sensor waits for the serial clock to be provided by the host on the signal SCLOCK_IN

for 100ms.

 If a clock is not provided, the sensor switches to operate in the final mode (quadrature or

serial).

 Upon detecting a serial clock on SCLOCK_IN, the sensor returns the clock to the host on

SCLOCK_OUT.

 Within the first 500ms after the serial clock is provided by the host, SCLOCK_OUT may

be unstable.
