8.1 RESET Switch and LED indicator
The RESET switch [SW2] provides for manual application of the RESET input signal. The S32K3 MCU will drive the RESET signal to
reset the EVB board peripherals. The RESET LED indicator [D22] will be ON for the duration of the RESET signal. This operation indicates
the S32K344 MCU is in the Reset state.
