I'm developing for a CYPD4225-40LQXI.  The datasheet says that 30 pins are available for GPIO.  It isn't clear exactly which pins these are.  I'm currently assuming all are except for the 5 power pins, the XRES pin and the 4 CC pins.  Is this incorrect?  There are a number of pins that are not listed as GPIO, such as VBUS_P_CTRL_P, which seem to be used as GPIO in the firmware.

Also, can all GPIO pins be used as an input to the ADC?

Hi,

You can check the pin diagram of CYPD4225 in PSoC Creator. All blue and black pins can be configured as GPIO. They can all be configrued as input to ADC.
