Notes:
1. Data based on characterization results, tested in production at V_DD max. and f_CPU max.
2. Measurements are done in the following conditions:
- Program executed from RAM, CPU running with RAM access. The increase in consumption when executing from Flash
is 50%.
- All I/O pins in input mode with a static value at V_DD or V_SS (no load)
- All peripherals in reset state.
- LVD disabled.
- Clock input (OSC1) driven by external square wave.
- In SLOW and SLOW WAIT mode, f_CPU is based on f_OSC divided by 32.
To obtain the total current consumption of the device, add the clock source (Section 12.5.3) and the peripheral power
consumption.
