I am taking current measurements of my PSoC5LP running under different conditions right now. The power estimator spreadsheet seems to underestimate the contribution caused by increasing the Bus Clock.
In the spread sheet there is a field for CPU Speed, if I program the PSoC5LP to run at 12 MHz, the current that I measure is what I would expect if I was running at 24 MHZ. If I increase the Bus Clock to 24 MHz, I measure a current similar to what the spreadsheet estimates at 48 MHz.
Is the CPU Clock really twice the bus clock? If this is so, can someone show me were this is documented at?
