I am designing a system with the STM32F407ZET. I need 3 ADC inputs. I only see ADC12_INx, ADC123_INx and ADC3_INx inputs. What does this mean? ADC12_INx inputs are connected to ADC1 and ADC2. ADC123 to ADC1, ADC2 and ADC3. And ADC3_INx is only for ADC3?
Can I use 1 ADC123_INx input and use this input for 'triple interleaved mode'?

I use the SPI port for a LCD with SPI interface. It only needs the SCK and MOSI. Can I use the MISO for another purpose and still use the SCK and MOSI in normal SPI mode (not bit banging!!)?

Thanks in advance for your help.

Kind regards,
