I bought a stellaris launchpad evaluvation board(LM4F120H) and firstly i was checking the current consuption in different frequencies.I varried the frequencies using the function "sysctlclkset().When i plot the reading for 40,25,20,10,5MHz i got linear variation in current-frequency.But when i plotted for 50 MHz it showes a current less than for 40MHz frequency.I varried the frequency by changing the PLL Dividing factor.
