For each of the powerdown modes – Static or Powerdown-Grid Off, the device PRCM will control whether clocks are gated, or whether supplies are reduced or removed.
In the case of “Powerdown-grid off”, a full power-on-reset sequence is required before re-booting and resuming functional operation.
In the static powerdown modes - the DSP recognizes new level interrupts while in a clock-gated state (and drive wakeup request). During this powerdown mode all internal state will be retained, including DSP C66x CorePac, interconnect, EDMA, memories, etc.
The following protocols are implemented with PRCM:
The Master standby and slave idle protocols behaviour is controlled in the DSP_SYS_SYSCONFIG register.
