Hello,
I have yellow text color ports when the CSD sensors are placed(P1[0 - 4], P1[7], P2[0 - 7]).
Please see below. The device is CY8C4124LQI-S413.
The PSoC Creator user guide has the following instructions:
This just tells me that there are other analog resources, and I don't think I should be careful as a CSD, is that correct?
Best regards,
Yocchi

Yes, that's correct.
ADC is sometimes more sensitive to noise or resistors on the sensor's pins and it will take more risk for the ADC result.
That's why it should be assigned to the port connected to AMUXBUS.

Yes, that's correct.
You don't have to take care of them, except SAR ADC.

Hello Aiko-san,
Thank you very much for you reply.
Are you saying that SAR ADCs are excluded because CapSense and SAR ADCs use AMUXBUS-A and AMUXBUS-B?
Is there any guidance on using both SAR ADC and CapSense?
Best regards,
Yocchi

Hello Aiko-san,
Thank you very much.
We will ask you about the error of ± LSB when we come to the detailed design.
Best regards,
