Detailed Description:
WDOG tested in SystemInit() function (system_S32K116.c) after POR.
For debugging purposes:
- WDOG counter reference clock is pre-scaled to slow the test (CS_PRES = 1).
- During CNT_LOW test, BLUE LED (PTE8) ON.
- During CNT_HIGH test, RED LED (PTD16) ON.
- Once both tests have passed, GREEN LED (PTD15) ON.
If either of the test fails, WDOG will stay in its default configuration and rest the MCU.

Test HW: S32K116EVB-Q048 REV.B
MCU: S32K116 0N96V
Debugger: S32DSR1, OpenSDA
Target: internal_FLASH

Hi,
The unlock write is indeed unnecessary since CS_ULK = 1 our of reset.
Nothing happens, it unlocks already unlocked WDOG registers and continues.

Hi Daniel,
Can I apply this example for S32K144EVB?
