4. Present design

5. Present implementation

6. Design consideration Wake up point
Active mode : Radio on, peripherals active
PM2 : Digital regulator off, oscillator off
32k XOSC, POR, sleep timer, ext interrupt active
RAM and register retention
Wake up method
Sleep timer : periodic
Motion interrupt : event sensitive
