What is the frequency range of the VLO clock on the MSP430FR2353?

In the DS is states only a TYP value of 10KHz.

Thanks.

FYI Since the VLO is optimized for low-power applications, it does not have the best accuracy as is. Across supply voltage, temperature range, and process variation the VLO frequency can vary up to +/- 50%.

I think your customer would be most interested then in the VLO calibration app report which shows customers how to calibrate the VLO using another more accurate internal oscillator in order to use the VLO in a low-power and high-accuracy application:
