3. SYSCLK must be at least 32 kHz to enable debugging.
4. Based on device characterization data; Not production tested. Does not include oscillator supply current.
5. IDD can be estimated for frequencies
6. Idle IDD can be estimated for frequencies
Supply Sensitivity
Frequency Sensitivity
frequency sensitivity number for that range. When using these numbers to estimate I
estimate should be the current at 50 MHz minus the difference in current indicated by the frequency
sensitivity number. For example: V
frequency sensitivity number for that range. When using these numbers to estimate Idle I
estimate should be the current at 50 MHz minus the difference in current indicated by the frequency
sensitivity number. 
For example: V
