2—SOFTWARE
To generate a single frequency tone encode the bits as follows:
Bit 0
0
Bits 1-5
3–30
The value in bits 1–5 is multiplied by 100 to generate the required frequency (300Hz–3000Hz).
Bits 6-7
0
The VoiceDSP processor does not check for the validity of the tone specification. Invalid specification
yields unpredictable results.
Example
GTD
Returns the time and day as a 2-byte value. time_day_option may be one of the following:
Any other time_day_option returns the time-and-day stamp of the current message.
Time and day are encoded as follows:
Bits 0–2
Day of the week (1 through 7).
Bits 3–7
Hour of the day (0 through 23).
Bits 8–13
Minute of the hour (0 through 59).
Bits 14–15

If the current message is undefined, and time_day_option is 1, an ERR_INVALID error is reported.
Get the system time and day.
Get the current message time-and-day stamp.
The time was not set before the current message was recorded.
The time was set, i.e., the SETD (Set Time of Day) command was executed.
