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.
