On A/D input voltage is 0V to Vcc or Vref if Vref is less then Vcc
Negative voltage can not be measured.

Hi,
I'm not sure what you want me to do about it?

Re: SUB-20 Slave Mode

Hi,
Let's increase the speed. Please try 250KHz and 400KHz.

Our SPI module is bidirectional. It has double buffer in one direction but not in another. This is the reason I think.
