1.1 End Code
The end code is used at the completion of a phrase. The MSM6650 family recognizes the end code
which is necessary when the edit ROM contains only a single phrase. When the maximum number
of phrases is selected (8) the end code is unnecessary.
1.2 Silence Insertion Code
Silence insertion code inserts silence in the specified channel, reducing voice data.

The channel for silence insertion is specified in the command data, while the silence time is set in the
address data.
Command data bit O7 (CH) specifies into which channel silence will be inserted, a "1" in data
bit O7 selects channel 1 while a "0" selects channel 2.
Silence time is set at the address settings of phrases shown in Table 4.
Minimum Silence Time .... 16.384 ms
Maximum Silence Time.... 2.1 sec.
The formula to set the silence time is shown below.

1.3 BEEP Tone Code
The BEEP tone code produces a BEEP tone from an internal circuit which is independent of the
ADPCM circuitry. The sound volume and frequency of a BEEP tone is set in command data, while
the playback time of a BEEP tone is set in the address data.
The BEEP tone can be set only in channel 1.
The sound volume is set at data bits O3, O2 and the frequency is set at data bits O1, O0.
