Tool/software:

Where can I get a definition of the bits in register AUX_DDI0_OSC ?
I don't see this register defined in the Reference Manual

Hi Dave,

The AUX registers are for the Sensor Controller (Chapter 17 of the TRM) and does not typically detail the registers involved with this separated core. Do you have any specific questions concerning the Sensor Controller?

Ryan

I am trying to find a way to determine that the 32KHz crystal is installed and working on a board, for production test.
I'm thinking that maybe setting the RTC clock source might be one way to do it.

I believe OSCClockSourceGet from the TI driverlib APIs is what you are looking for. You would us OSC_SRC_CLK_LF as the parameter and expect to receive OSC_XOSC_LF for the 32 kHz crystal, OSC_RCOSC_LF would be the internal oscillator. You can also try to use OSCClockSourceSet if the external 32 kHz crystal is not selected as part of your CCFG.

Ryan
