I am using TC275 shieldBuddy, and I ‘d like to do an adc scan with the fast compare mode. I am using the background scan now and I have put the reference value into the group result register. But it seems like the sampled value does not compare with the reference value I set, but a value which represents a very low voltage, because no matter how large value I set, the value in the FCR register is 1. Only when I connect the scanning pin (input pin) with the ground, will the value in the FCR becomes 0.

Here are my codes:
