dbgmodrst
The DBGMODRST register is used by software to trigger module resets (individual module reset signals). Software explicitly asserts and de-asserts module reset signals by writing bits in the appropriate *MODRST register. It is up to software to ensure module reset signals are asserted for the appropriate length of time and are de-asserted in the correct order. It is also up to software to not assert a module reset signal that would prevent software from de-asserting the module reset signal. For example, software should not assert the module reset to the CPU executing the software.
Software writes a bit to 1 to assert the module reset signal and to 0 to de-assert the module reset signal.
All fields are only reset by a cold reset

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
