To erase partial memory, specify the start (F) and end addresses (or start address and number of
sectors to erase), and then click on ‘Erase Memory’ (C) ; while the erasing is in progress, status bit
CMD_BSY (E) goes high. The minimum erasable memory size is one sector (4k bytes).
Memory contents can be read back and either displayed on screen or saved as a file on PC.
To display the memory contents on screen:
To save the memory contents on PC:
Memory contents can be updated by digital-write from either a file on PC or from the screen.
To update the memory contents from a file:
To update the memory contents from the screen:

1. Want to erase the whole chip and then download a file from PC:
2. Just overwrite partial memory contents by a file from PC (the default):

Specify the start (G) and end addresses (or start address and number of bytes to read).
Specify to display on screen (H) (the default).
Click on ‘Digital Read’ (A).
Specify the start (G) and end addresses (or start address and number of bytes to read).
Specify to save as a file (H). Click on ‘Select File to Save’ (J) to specify the path and
filename.
Click on ‘Digital Read’ (A).
Read out the ISD15100 data and have it displayed on screen as described above.
Edit the data contents on screen.
Specify to update the memory contents from screen (L).
The start (N) and end addresses will be automatically matched.
Click on ‘Digital Write’ (B); VPE accomplishes this task via the help of PC:

Users can click on ‘Read ID’ (I) to get the memory size.
Check ‘Mass Erase/Prog’ (K).
Specify to update from a file (L) (the default). Click on ‘Select File to Open’ (M) to
specify the path and filename.
The start (N) and end addresses will be loaded automatically.
Click on ‘Digital Write’ (B), and VPE will chip-erase the whole memory and then
download the file to the ISD15100.
Uncheck ‘Mass Erase/Prog’ (K).
Similar procedure as the above. VPE accomplishes this task via the help of PC:
The first sector (sector 0) is about the ISD15100 configuration. Do not mess it up.
1. If needed,
2. Sector-erase the sector.
3. Download the buffer to the sector.
4. Repeat the above steps.
