WIRELESS & SENSING PRELIMINARY DATASHEET
4.2.8.3. Timers
Two timers (Timer1 and Timer2) are also available in order to define periodic sequences. These timers are used to
generate interrupts, which can trigger transitions of the Sequencer.
T1 interrupt is generated (Timer1Resolution * Timer1Coefficient) after T2 interrupt or SequencerStart. command.
T2 interrupt is generated (Timer2Resolution * Timer2Coefficient) after T1 interrupt.
The timers’ mechanism is summarized on the following diagram.

Figure 23. Timer1 and Timer2 Mechanism
Note The timer sequence is completed independently of the actual Sequencer state. Thus, both timers need to be on to
achieve periodic cycling.
