==Watchdog Handling==
*The device has 2 independent watchdogs: IWDG and 2 windowed watchdogs: WWDG.
*The watchdogs are stopped during flash programming.

==Multi-Core Support==
Before proceeding with this article, please check out the generic article regarding Multi-Core debugging [[Multi-Core_Debugging | here]].<br>
The N32H78x family comes with a variety of multi-core options.<br>
Some devices from this family feature a secondary core which is disabled after reset / by default.<br>
Some of the are available with enabled ''lockstep'' mode, only. <br>

In below, the debug related multi-core behavior of the J-Link is described for each core:
===Main core===
====Init/Setup====
*A Boot-ROM API function is executed to determine RDP protection level and the user is prompted to perform RDP regression (erases flash memory content and removes readout protection).
====Reset====
*Device specific reset is performed: the core is stopped using the breakpoint unit after the Cortex-M system reset.
====Attach====
*Attach is not supported because the J-Link executes Boot-ROM API functions during initialization.
===Secondary core(s)===
====Init/Setup====
*A Boot-ROM API function is executed to determine RDP protection level and the user is prompted to perform RDP regression (erases flash memory content and removes readout protection).
====Reset====
*Device specific reset is performed using custom core reset.
====Attach====
*Attach is not supported because the J-Link executes Boot-ROM API functions during initialization.

==Device Specific Handling==
===Option bytes programming===

==Limitations==
===Security===
*Device supports readout protection (RDP). If a RDP1 level protected device is detected, the user will be prompted to unsecure the device.
