Other Parts Discussed in Thread: TM4C1231H6PM

I'm using an LM4C1231H6PM CPU. I've wasted over an hour trying to find what class of device it is, any help here?

Thanks

Hello Doug,

Did you mean TM4C1231H6PM? When you mention class of device, can you be more specific: The device is a Cortex M4F CPU. The Device Class as per SYSCTL.DID0 is a TM4C123 Class.

Regards
Amit

Sorry, yes it's the TM4C1231H6PM. I'm reading the TivaWare Driverlib documentation and ran across "This function cannot be used with Blizzard-Class Devices". So is my CPU a Blizzard-Class device?

Thanks
Doug

Thank you Amit. I was looking at the SysCtlClockFreqSet() function.

Hello Doug,

Yes. This function is for TM4C129 device class only. BTW, thanks for carefully going through the documentation. Do let us know if there are other issues you see and post it so that we correct documentation.
