6-26 DSP Commands
D3h
Output
D3h
Remarks
The DSP takes a maximum of 220 milliseconds to complete this command.
Some important notes:
1. On version 1.xx, the DSP will pause the DMA transfer after executing this
command.
2. On DSP version 4.xx, this command has no practical effect on the output signal.
However, it will still set to 'Off' the DSP's internal speaker On/Off flag so that
command D8h, Get speaker status, will return the correct status.
