Hello
While checking the technical references and datasheet for the launchpad CC3200 i noticed that the features described that the Cortex M4 processor for applications ran at 80Mhz, but as i read further it would state that the cc3200 launchpad used an external 40mhz crystal for its operation.
The last statement was further validated when i tested the UtilsDelay function from the Peripheral API which takes 3 cycles per iteration loop: i would get a 1 second delay by giving the UtilsDelay function a parameter of 13,333,333 :
* 0.999 approx 1 second = (3cycles * (13333333) ) / (40mhz)
So my question is:
- What is the real operation frequency of the cc3200 launchpad?
- Does it have an internal oscillator that can work without the need of a crystal at 80mhz?
- Is there a register i need to configure to get different frequencies of operation? (Let us say.. if i have a 80mhz oscillator but i want to run at perhaps 20mhz, what register do i need to set to do so?)
I am fairly new to the whole Microcontrollers world so i hope my extremely basic questions won't be a nuissance.
Regards!
