I'm working on examining the current drain on a new project, and am coming up with some odd results. Its my understanding that IDLE 3 turns off the PLL, so it shouldn't matter what speed I have reviously set the PLL to, right? my test powers up the peripherals, but then drops into an infinite loop with IDLE 3 in the middle of it. I am seeing about a 130mA current draw difference between setting the PLL to its defauly /2 state and x8 mode (19.2MHz clock). Is this normal? According to the c5416 docs I should be seeing a max of about 100mA of drain when running at 160MHz, but I seem to be able to easily exceed this. Thanks, Brian ----------------- Brian C.
