Hello,
I have a custom circuit where I used a 20 mhz oscillator fed into osc0 and with osc1 left floating.
I have been initializing the programs with:
ROM_FPUEnable();
ROM_FPULazyStackingEnable();
ROM_SysCtlClockSet(SYSCTL_SYSDIV_2_5 | SYSCTL_USE_PLL | SYSCTL_XTAL_20MHZ | SYSCTL_OSC_MAIN);
Before I was using 16mhz crystals for my custom tiva circuits, but now I am using 20mhz source, what changes do I have to make, if I want to run the tm4c123gh6pm 'n the fastest mode?
I only changed the SYSCTL_XTAL_16MHZ to SYSCTL_XTAL_20MHZ, leaving SYSCTL_SYSDIV_2_5 unchanged.
I also have tested the USB, and it also does work. Is there anything I need to change apart from these?
Best Regards,
C.A.
