Once code memory is programmed, the contents of
memory can be verified to ensure that programming
was successful. Verification requires code memory to
be read back and compared against the copy held in
the programmer’s buffer.
The READP command can be used to read back all the
programmed code memory.
Alternatively, you can have the programmer perform
the verification once the entire device is programmed
using a checksum computation, as described in
Section 6.8 “Checksum

5.6.1
The panel architecture for the data EEPROM memory
array consists of 128 rows of sixteen 16-bit data words.
Each panel stores 2K words. All devices have either
one or no memory panels. Devices with data EEPROM
provide either 512 words, 1024 words or 2048 words of
memory on the one panel (see

5.6.2
The programming executive uses the PROGD command
to program the data EEPROM.
the flowchart of the process. Firstly, the number of rows
to program (RemainingRows) is based on the device
size, and the destination address (DestAddress) is set
to ‘0’. In this example, 128 rows (2048 words) of data
EEPROM will be programmed.
The first PROGD command programs the first row of
data EEPROM. Once the command completes
successfully, ‘RemainingRows’ is decremented by 1
and compared with 0. Since there are 127 more rows
to program, ‘BaseAddress’ is incremented by 0x20 to
point to the next row of data EEPROM. This process is
then repeated until all 128 rows of data EEPROM are
programmed.
