2.4.14
The timing and data control unit contains a wake-up logic unit, an I
interface, a “data valid” detection unit and a set of configuration registers as shown in the
subsequent figure.

The I
parameters at any time.
It is possible to set the device in three different modes: Slave Mode, Self Polling Mode and Timer
Mode. This is done by a state machine which is implemented in the WAKEUP LOGIC unit. A
detailed description is given in Section 2.4.16.
