Resolved! How do the GPIOs actually work?

That question started bothering me when I was struggling with TLE493D that started interrupting using the i2c clock line.It looked like the i2c in the F429 was gone bananas and keeping the i2c stuck (busy).I was thinking of feeding the i2c the clock ...

STM32F103RCT6 I2C SLAVE transmitter CAN NOT GENERATE ACK

Using STM32F105RBT6 with a 4-pin oscillator?

I'm using a STM32F105RBT6 in LQFP64 package in a project. The datasheet suggests using a crystal or resonator. I want to use a 4-pin oscillator that has a single output pin. Is this possible and if so where do I connect it?Thanks.
