Notes: 1. These I/O lines have permanent non-programmable maximum drive (MaxDRV).
2. Refer to “Peripheral Signal Multiplexing on I/O lines” tables in the section “Peripherals”.
3. Relaxed mode applies for cases of higher output current on the I/O lines that override standard V
OL
and V
OH
definitions.
45.4.2 I/O AC Characteristics
Criteria used to define the maximum frequency of the I/Os:
Output duty cycle (40% - 60%).
Minimum output swing: 100 mV to VDDIO - 100 mV.
Minimum output swing: 100 mV to VDDIO
- 100 mV.
Addition of rising and falling time inferior to 75% of the period.
Notes: 1. Pin Group 1 = PA0, PA29, PB13, PC0, PC5 pins.
2. Other pins, Low Drive Settings.
3. Other pins, Medium Drive Settings.
