The ID_DISPLAY_DATA flow described below allows the user to read data in the Flash memory
or in the EEPROM data memory. A blank check command on the Flash memory is possible with
this flow.
This operation can be executed only with a device previously opened in communication.
To start the reading operation, the Host sends a “Display Data” CAN message (Id_display_data)
with the area memory selected, the start address and the end address passed in parameter.
The device splits into block of 8 bytes data to transfer to the Host if the number of data to display
is greater than 8 data bytes.
Notes:
The device has two possible answers:
•
•
Answer to a read command:
If the chip is protected from read access an “Error” CAN message is sent (see Section “Error
Message Description”, page 22).
Otherwise:
for a display command the device starts to send the data up to 8 by frame to the host. For a
blank check command, the device sends a result OK or the first address not erased.
1.
2. The Address_start gives the start address to read.
3. The Address_end gives the last address to read.
