So this is probably a stupid question but I just want to confirm before purchasing the MCU. For the project I need an MCU that is capable of producing I2C (this is supported by this MCU), can generate a PWM signal (is also supported) and has 16 digital PINS. In the datasheet it says there are 22 GPIOs so that should be 2 for I2C and 1 for PWM leaving 19 and that is of course even more than enough. However the part that is confusing me is this image in the datasheet. There are only 13 pins assigned as digital. Can I use pins 02-07 as digital, furthermore can I use pins PA08 and PA09 as digital (they are oscillator pins)?
Thanks in advance.
