Why K64 pin 36/J3/H3 has two ADC0 SE names?

[haizhouli]

We are using K64 121 XFBGA package. The pin H3 was used as ADC.

The K64 reference manual shows that this pin can be used as either ADC0_SE16 or ADC0_SE21.  Why one pin was assigned to two channels and both are in ADC0?

Hi Haizhou Li,

   You are really very careful in reading the reference manual, that's very good!

  About this question, I already test both ADC0_SE16 and ADC0_SE21 in our TWR-K64, the result is both pin can work when it is configured as the ADC input pin.

  About the reason of assigning two ADC0 channels in one pin, we still don't clear about it, now, I already transfer this question to our according engineer, and waiting for their reply.

But it may need time to get feedback, when I get the feedback, I will let you know.

  So, now please let us wait patiently!

Thanks for your question!

Best Regards,

Jingjing
