Notes:

1. Based on device characterization data; Not production tested.

2. SYSCLK must be at least 32 kHz to enable debugging.

3. The values in this table are obtained with the CPU executing an “sjmp $” loop, which is the compiled form of a while(1)

loop in C. See the power measurement code examples for more information.

4. Includes oscillator and regulator supply current.
