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

NOTES:
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 A.1.4 Current Injection, for more details
3. Parameter only applies in STOP or Pseudo STOP mode.
