1. Typical values characterized at 25°C and VDD = 3.6 V unless otherwise noted.
2. Open drain outputs must be pulled to VDD.
3. Analog pins are defined as pins that do not have an associated general purpose I/O port function.
4. Digital pins have an associated GPIO port function and have 5V tolerant inputs, except EXTAL and XTAL.
5. Internal pull-up/pull-down resistors disabled.
6. Characterized, not tested in production.
7. Examples calculated using VIL relation, VDD, and max IIND: ZIND=VIL/IIND. This is the impedance needed to pull a high
signal to a level below VIL due to leakage when VIL < VIN < VDD. These examples assume signal source low = 0 V.
8. Measured at VDD supply voltage = VDD min and Vinput = VSS
9. Measured at VDD supply voltage = VDD min and Vinput = VDD

All specifications except tPOR, and VLLSx→RUN recovery times in the following table
assume this clock configuration:
• CPU and system clocks = 100 MHz
• Bus clock = 50 MHz
• FlexBus clock = 50 MHz
• Flash clock = 25 MHz
• MCG mode: FEI
