Command Header	Description
0x00010000	GetWakeStatus. This loads PDN_WAKE_ENABLE and PDN_WAKE_REASON, then writes them to cmdreplyword[2] and cmdreplyword[3].
0x00020080	ConfigureWakeEvents. PDN_WAKE_REASON = cmdword[2] & cmdword[1]. This then writes cmdword[1] to PDN_WAKE_ENABLE. PDN_WAKE_REASON = cmdword[2] & ~cmdword[1].
0x00030040	Acknowledge. Writes cmdword[1] to PDN_WAKE_REASON.

Command Header	Description
0x000100C0	(bool enable, bool reset, bool deassertResetAfterReset) Enables and/or resets the DSP and/or holds it in reset

0x00020040	This sets bit1 in PDN_I2S2_CNT to u8 cmd+4.

Command Header	Description
0x000100C0	(bool enableClock, bool resetEngines, bool resetRegisters) Enables and/or resets the GPU, see PDN_GPU_CNT

Command Header	Description
0x00010040	This sets bit0 in PDN_CAMERA_CNT to u8 cmd+4.
