The commands are listed in alphabetical order.
The execution time for all commands, when specified, includes the time required for the microcontroller
to receive the return value, where appropriate.
The execution time does not include the protocol timing overhead, i.e., the execution times are mea-
sured from the moment that the command is detected as valid until the command is fully executed.
NOTE:
CCIO
Configures the voice sample paths in various states. It should be used to change the default VoiceDSP
processor configuration. It is relevant only when two codecs are used and speakerphone is connected.
The config_value parameter is encoded as follows:
Bit 0
Loopback control.
Bit 1
Codec input control.
Bits 2–3
Codec output control.
Bits 4–7
Reserved.

COMMAND DESCRIPTION
Each command description includes an example application of the command. The examples
show the opcode issued by the microcontroller and the response returned by the VoiceDSP pro-
cessor. For commands which require a return value from the processor, the start of the return
value is indicated by a thick vertical line.
Loopback disabled (default).
Loopback enabled. In the RECORD state, the input samples are echoed back, unchanged
(i.e., no volume control), to the same codec.
Input is received via the line codec (default).
Input is received via the speakerphone codec.
In PLAY, IDLE, SYNTHESIS and TONE_GENERATE states, output is to both codecs. In RECORD
state, output is to the non-input codec (no volume control). If the loopback control bit is set,
output in RECORD state is to both codecs as well (default).
Output in all states is to the line codec.
Output in all states is to the speakerphone codec.
Output in all states is to both codecs.
