The supported power-down modes are:
Powerdown-retention mode is NOT supported by DSP subsystem. The DSP recovery from the Powerdown-grid OFF mode requires full boot.
The DSP C66x CorePac natively supports “CLKSTOP/Static Powerdown” and “POWERDOWN (Grid off)” modes of operation. Once the device PRCM restores clocks and power supply, then the DSP C66x CorePac can exit static-powerdown.
The DSP_SYSTEM wakeup logic is implemented in the "always-on" clock / power supply domain. This logic monitors new interrupts / events and will drive the IDLE wakeup request when a new interrupt / event occurs.
