*****************************************************************************
*Detailed Description:
*This example will show you how to configure Sbc_fs23 Driver.
*It initialization of Sbc_fs23 with watchdog window disabled. The Sbc_fs23_InitDevice() must be done within the dedicated 256 ms INIT window.
*It Disable regulator V2, then re-enable it again. FS0b pin is asserted due to V2 Undervoltage reaction setting configured in FailSafe Init Configuration tab.
*If the example runs without errors, the D12 LED on S32K31XEVB-Q100 will light up Green; otherwise, it will light up Red.
*The SPI data between FS23 and S32K311 are captured and attached to the project.
*Use the analog input of a logic analyzer or an oscilloscope to monitor the signals of FS23_V2 (TP27) and FS23_FS0 (TP8) on the KITFS23SKTEVM board.

*Test HW:
* S32K31XEVB-Q100 Board SCH-55131 REV A P32K311HV 0P98C
* KITFS23SKTEVM Dev-kit SCH-53096 REV B2 MFS2320BMBB1EP
* My S32K31XEVB-Q100 has an onboard PFS2320A0L1W1, but Step 13/14 of AN14041 mention that A0 devices are not supported, so S32K311 communicate with the FS23 on the KITFS23SKTEVM.
