1. Given in Table 9.2 on page 86.
2. SYSCLK must be at least 32 kHz to enable debugging.
3. Based on device characterization data; Not production tested.
4. Normal IDD can be estimated for frequencies <= 15 MHz by simply multiplying the frequency of interest by
5. Idle IDD can be estimated for frequencies <= 1 MHz by simply multiplying the frequency of interest by the
Supply Sensitivity (Note 3) F = 25 MHz
Frequency Sensitivity
the frequency sensitivity number for that range. When using these numbers to estimate I
estimate should be the current at 25 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 25 MHz minus the difference in current indicated by the frequency sensitivity
number. 
