Control Commands
You can control Record/Playback operations by using 4-bit commands through the serial interface.
1. Control Commands-Recording
The following section describes commands used to control recording:
1.1. REC Command (1XH)
By using the first 4 bits of this command, you can initiate recording, starting at the specified Start Address and
recording lasts up to the specified Stop Address. When the specified Stop Address is reached, recording
automatically ends up.
4-bit data preceded is to define a sampling frequency, as shown in the table below. When the sampling frequency
is not defined with this command, recording is made at the last defined sampling frequency.
When reset and powered up, recording is made at 6.4 kHz (default) sampling frequency.
You can specify the Start and Stop Addresses for a recording session by using the STADR and SPADR commands.
See 1.4 and 1.5 of this Data Sheet for further details on the STADR and SPADR commands.
1.2. STOP Command (3H)
You can stop recording by using this command. The data following to this command is disregarded.
1.3. PAUSE Command (4H)
You can suspend recording temporarily by using this command. The data following to this command is
disregarded.
To re-input the command resumes the suspended operation. If the STOP command is input while recording is
suspended by the PAUSE command, the LSI shifts to Record Ending operation and then terminates recording.
