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
communication (data sent equal to 55h).
3. Data based on a differential IDD measurement between reset configuration and continuous A/D
conversions with amplifier off.

1. Guaranteed by design. Not tested in production.
2. Data based on typical application software.
3. Time measured between interrupt event and interrupt vector fetch. Dtc(INST) is the number of tCPU cycles
needed to finish the current instruction execution.
