Pin Configuration
After reset, all pins are configured as input (except supply pin) with one of the following settings:
• Pull-up device enabled only (PU)
• Pull-down device enabled only (PD)
• Input with both pull-up and pull-down devices disabled (I)
• Output with output stage deactivated = high impedance state (Hi-Z)
The functions and default states of the TLE9871QXA20 external pins are provided in the following table.
Type: indicates the pin type.
• I/O: Input or output
• I: Input only
• O: Output only
• P: Power supply
Not all alternate functions listed.
