How to set the system clock frequency through registers in LPC845brk

tomato — Tue, 10 Jan 2023 15:04:20 GMT

Hello,

I see that in MCUexpresso IDE there is this useful tool to change the system clock frequency

Can you tell which registers are changed when I set for instance 24MHz?

Could you please read the LPC845 User Manual Chapter 8: LPC84x System configuration (SYSCON) (8.6 Register description) and Chapter 9 LPC84x FRO API ROM routine ()?

There you may find more information about the FRO_OSC and System clock generation trough the registers.

Best regards, Raul.
