MSP430F5438A: XT1 External Crystal Not Working

Part Number: MSP430F5438A

Tool/software:

Hello,

We are currently using the MSP430F5438A XT1 external crystal oscillator 10Mhz.

I looked at the slau208q.pdf manual. When writing about XT1DRIVE, it only talks about the driver configuration in XT1 LF mode.

Question 1: In XT1 HF mode, is the configuration of this drive capability still valid?

Question 2: In XT1 HF mode, 10M crystal oscillator. Can XT1DRIVE be set to 10,11?

Question 3: When using an oscilloscope to detect the trigger signal sent by MSP430F5438A to the 10M crystal, no trigger level was found. When working normally, a 3.3v high pulse trigger signal can be seen output. Do you know why this could be happening?

Question 4: Is it better to use XT2 in high frequency mode? The configuration of XT2DRIVE is definitely for high frequency.
