Electrical characteristics

10.3.6 I/O port pin characteristics

General characteristics

Subject to general operating conditions for VDD and TA unless otherwise specified. All

unused pins must be kept at a fixed voltage: using the output mode of the I/O for example or

an external pull-up or pull-down resistor.
