PDN PTM Service "pdn:s"[edit]
| 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. |
PDN DSP Service "pdn:d"[edit]
| Command Header | Description |
|---|---|
| 0x000100C0 | (bool enable, bool reset, bool deassertResetAfterReset) Enables and/or resets the DSP and/or holds it in reset |
PDN I2S Service "pdn:i"[edit]
| Command Header | Description |
|---|---|
| 0x00010040 | This sets bit0 in PDN_I2S1_CNT to u8 cmd+4. |
| 0x00020040 | This sets bit1 in PDN_I2S2_CNT to u8 cmd+4. |
Used by Codec Services.
PDN GSP service "pdn:g"[edit]
| Command Header | Description |
