ERR_TIMEOUT
Time-out error. Depending on the VoiceDSP processor’s state, more than 100 milliseconds elapsed be-
tween the arrival of two consecutive bytes (for commands that have parameters).
ERR_INVALID
Command can not be performed in current context.
Example
GI
Returns the 16-bit value specified by item from one of the internal registers of the VoiceDSP processor.
item may be one of the following:
The return value is unpredictable for any other value of item.

The duration of the last detected DTMF tone, in 10 ms units. The return value is meaningful
only if DTMF detection is enabled, and the status word shows that a DTMF tone was de-
tected.
The duration of the last detected busy tone in 10 ms units.
The energy level of the samples in the last 10 ms.
The energy level of the samples, in the last 10 ms, that are in the frequency range de-
scribed in Figure 2-1. The return value is meaningful only if one of the tone detectors is
enabled (bits 0,1 of the detectors mask; see the description of SDET command).

Get the VoiceDSP processor error word (typically sent after GSW when EV_ERROR is
reported in the status word).
The VoiceDSP processor responds: ERR_OPCODE:
