Notes:
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.
