Hi,
Now, we use STM32G070RB.
Please let me make clear about internal PU/PD resistor setting on PA8.
Although we set internal PU res from GPIOA_PUPDR, measured voltage is near 0V at this port.
We found this is because the PD res that is set by SYSCFG_CFGR1[9].
After assert this bit, we could get 3.3V(pulled-up by internal res by GPIOA_PUPDR).
Actually, there is priority for these PU setting and PD setting on this port?
Br,
Yuji
