MSP430F417: 48 pin has no output signal

Dear Team,

Hope you are doing well!

Our customer recently has met a problem that the 48pin of MSP430F417 has no signal output.

The are following the steps shown like blow:

1. Connected MSP430 with power source, connected and set the frequency indicator.

2. Turned on the power, waiting for the system initialized. When there was waveform on oscilloscope and frequency indicator, adjusted the valuable C9 to set the frequency in the range of 32.7679-32.7681 KHz.

The majority of MSP430F417 can output signal normally and a little bit that could not output the signal at 48pin.

The schematic diagram is shown as below；

Could you please help me to have a check?

Thanks a lot!

Best regards,

Xenon Li
