Appendix A Electrical Characteristics
A.1.9 I/O Characteristics
This section describes the characteristics of all 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, “Current Injection”, for more details
3. Parameter only applies in STOP or Pseudo STOP mode.
