On the ‘Reserved Memory’ screen, users reserve memory sectors for message recordings:
Please note only ADPCM, (D)uLaw, and PCM compressions are supported for reserved messages,
not Enhanced-ADPCM or VBR.
To record (or playback) a message, the microcontroller simply issues a record (or playback) message
command with starting address pointing to the reserved initial address. VPE operations of reserving
re-recordable messages are similar to those of voice prompts. The reserved messages are also listed
on the ‘Voice Macro’ screen for voice macro script programming.
Memory sectors can also be assigned in Reserved Memory for digital read/write access for other
application tasks (User Data). To reserve empty memory sectors, click the button ‘Add Reserved
Memory’ (C) and then adjust the ‘Number of Sectors’ (D). To reserve (import) existing data, click the
button ‘Add Data’ (E); the file size will be shown on ‘number of sectors’ (F).

An Empty Message is an empty 4kByte memory sector reserved for message
recordings. An SPI record command pointing to the Empty Message starts the
message recording and will continue to record to the free memory sectors located in
Recording Memory if the message recording is over 4kByte.
Users can have a default message when reserving the memory sectors for a
message recording. For a re-recordable message, the first sector will be allocated in
‘Reserved Sectors’ (refer to Figure 2-7); the rest of the message will be allocated in
‘Recording Memory’.
