32.5 Power Consumption
The values are measured power consumption under the following
conditions, except where noted:
- VDD = 3V
- TA = 25°C
- OSC20M used as the system clock source, except where otherwise specified
- System power consumption measured with peripherals disabled and I/O ports driven low with inputs disabled
