The NRSTMODRST 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

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
