I am working on the development of SPC574K chip, but the debugger cannot connect with the chip successfully. When the chip is powered on, the crystal waveform is the first picture, which is normal. When I press the reset button or the connect button in the computer debugging software, the waveform of the crystal oscillator becomes the second picture. I want to know if the debugger's inability to connect to the chip is the reason, and why the reset makes the crystal oscillator work incorrectly.
