Appendix A Electrical Characteristics
A.1.9 I/O Characteristics
This section describes the characteristics of all 3.3V/5V I/O pins. All parameters are not always applicable,
e.g., not all pins feature pull up/down resistances.

1 _{Maximum leakage current occurs at maximum operating temperature. Current decreases by approximately one-half for each}
8°C to 12°C in the temperature range from 50°C to 125°C.
2 _{Refer to Section A.1.4, “Current Injection” for more details}
3 _{Parameter only applies in STOP or Pseudo STOP mode.}
