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 tempearture range from 50 C to 125 C.
2 Refer to Section A.1.4, âCurrent Injectionâ for more details
3 Parameter only applies in STOP or Pseudo STOP mode.
