Execution speed in VLPR Mode

[shrejjjhh]

Hi,

I am using MKL15Z128CAD4R. I have configured the controller to VLPR mode at 2MHz SystemCoreClock. But this increases the execution time and hence my application gets slower. Is there any way to increase the instruction execution speed? 

Regards,

Shrey

Hello Shrey,

In the reference manual you will find the following information in the table 5-1. 

You can increase the speed of the clock up to 4MHz. If you want to increase more the execution speed of the instructions then you will need to exit VLPR mode so you can speed the clock up to 48MHz. 

Link to the reference manual

Hope it helps!

Victor.
