== Channel 2 (Audio) == | |||
Channel 2 returns the DSP DRAM addresses of structures located in the [[DSP Memory Region]]. [[DSP:ConvertProcessAddressFromDspDram]] can be used to convert these addresses into virtual memory addresses. The list of addresses and the length of the list vary depending on DSP firmware version. | |||
== Channel 3 (Binary) == | |||
The purpose of channel 3 is unknown. The behaviour of this pipe varies depending on DSP firmware version. Observed behaviours include: | |||
* doing nothing. | |||
* echoing what is returned to it. | |||
* long strings of zeros. | |||
