TM4C129ENCPDT Crystal oscillator.

Alex Schoenheit

The oscillator just wouldn't start. I connected 8MHz Xtal to pins 88-89 with 15PF from each Xtal side to GND and 100R resistor from pin 89 to Xtal. Both pins output 3.3V, and this sounds strange as a normal oscillator should be biased in the middle of VDD rail, more like 1.5V. Anyone can explain?

Thanks in advance.
