4.1.4 Software shutdown
When the software executes the HIBERNATE instruction, the V
R
4102 places the DRAM in the self-refresh mode,
deasserts the MPOWER pin inactive, and enters the reset status.
Reset by software shutdown initializes all the internal statuses except the RTC timer and PMU.
After reset, the processor serves as the master of the system bus, the sequence of the cold reset exception is
executed, and accessing the reset vector in the ROM space is started. Because only part of the internal status of the
V
R
4102 is reset, completely initialize the processor in software.
