coldmodrst
The COLDMODRST register is used by software to trigger module resets. Writing 1 to any of these fields will cause the L2 or CPU POR reset signal to be asserted if that module is in WFI mode. The Reset Manager hardware will bring the module back out of reset after the appropriate amount of time.
All fields are only reset by a cold reset.
