the INIT command. If this bit is set during normal operation of the VoiceDSP processor, it indicates an in-
ternal VoiceDSP processor error. The microcontroller can recover from such an error by re-initializing the
system.
EV_DTMF
1 = Started detection of a DTMF tone.
Example
GT
Generates the tone specified by the 1-byte tone parameter. The VoiceDSP state changes to
TONE_GENERATE. The tone generation continues until an S command is received.
A DTMF or a single frequency tone may be generated as shown:
To generate a DTMF encode the bits as follows:

Get the VoiceDSP processor Status Word (typically sent after the MMRQST signal is asserted by
the VoiceDSP processor which indicates a change in the status word).
The VoiceDSP processor responds that the memory is full.
