How to configure the LPC802 to oscillate at the maximum frequency of 15MHz?

[leonardobarbosa]

Hi everyone!

I am developing a project with the LPC802 and would like to know how to configure the inner crystal to oscillate at 15MHz. From what I understand the FRO must be set to use the 30MHz and then divided by 2 to result in 15MHz. Reading the manual of the item I saw that it is possible to do this using an API that is in the ROM, but I did not succeed, could you help me?

Hi Leonardo Miguel,

Thank you for your interest in NXP Semiconductor products and 

the opportunity to serve you.

To provide the fastest possible support, I'd highly recommend you to refer to the demos in code bundle, in the demos, it illustrates the way of configuring a system clock frequency of 15 MHz.

Have a great day,
TIC
