Hello, what is the voltage level of the logical HIGH at the I/O output?
The datasheets "QuickLogic EOS S3 Ultra Low Power multicore MCU datasheet - Version 3.3d" and "QuickLogic EOSTM S3 Sensor Processing Platform Input/Output Multiplexor (IOMUX) User Guide Rev 1.1" do not provide information on this.

There are two banks of IO on the EOS S3. The supplies for the IO is named as VCCIOA and VCCIOB (1.8V - 3.3V). The logical "1" for input signal is 0.65 * supplied voltage. Logical "0" for input is 06v (max). Hope this helps.
