Since the pins IO3 and IO4 support analog input functionality and are limited to a certain
voltage range of V
to be determined according to following conditions:
• Maximum level of the expected foreign voltages
• Voltage range of IO3 and IO4 = V
The voltage on IO3 or IO4 is measured with a reference to VCM. Hence an input voltage

referenced to VCM. The unknown foreign voltage V
