12.8 I/O PORT PIN CHARACTERISTICS
12.8.1 General Characteristics
Subject to general operating conditions for V
Figure 61. Two typical Applications with unused I/O Pin
Figure 62. Typical I
Notes:
1. Configuration not recommended, 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 (see
based on design simulation and technology characteristics, not tested in production. This value depends on V
perature values.
2. The R
scribed in
3. To generate an external interrupt, a minimum pulse width has to be applied on an I/O port pin configured as an external
interrupt source.
