SuperPro 12mhz XTAL Registers.

Post by FIREWALL »

I finally got around to adding a 12mhz XTAL and load caps to one of my Super-Pros. Can you tell me the proper register values I have to set to run the SuperPro at 100mhz using the 12mhz Xtal I added? I am programming in C and I am looking at system_LPC175x6x.c but I am not sure what to change.

The clocks are setup in the SystemInit routine in each of the system_LPCxxxx.c file (system_LPC175x6x.c for the SuperPRO)

You need to enable the main oscillator, then set the PLL to multiply by the desired amount, the User Manual describes the settings.
