1. Data based on a differential IDD measurement between reset configuration (timer stopped) and a timer running in PWM

mode at fcpu=8MHz.

2. Data based on a differential IDD measurement between reset configuration and a permanent SPI master communica-

tion (data sent equal to 55h).

3. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions with am-

plifier off.
