Running KDS project for this part.
I find that the ADC analog pins voltage protect when input exceeds 1.6V approx.
VDD ,VDDA - 3.3V
VSS,VSSA - GND
Ran 8 and 16 bit configuration - Single ended 48Mhz clk ext
Jtag/uart/PDio all work as expected. Replaced IC same operation.
The lower 8 bits work in both configurations
until ADC input value reaches above 1.6V.
Is the 32QFN limited to half VDD input voltage for analog inputs and 8bit only?
Data sheet - VrefH and VrefL are connected to VDDA and VSSA respectively for this part.
