4.5.2
After the code memory is programmed, the contents of
the memory can be verified to ensure that the
programming is successful. Verification requires the
code memory to be read back and compared with the
copy held in the programmer‘s buffer.
The READP command can be used to read back all of
the programmed code memory.
Alternatively, you can have the programmer perform
the verification after the entire device is programmed
using a checksum computation.

The programming executive uses the PROGD command
to program the data EEPROM. Figure 4.7 illustrates
this process.
• First, the number of words to program
• The first PROGD command programs the first word
• Once the command completes successfully,
• Since there are 255 more words to program,
• This process is then repeated until all 256 words
4.6.2
Once the data EEPROM is programmed, the contents
of the memory can be verified to ensure if the
programming was successful. Verification requires the
data EEPROM to be read back and compared with the
copy held in the programmer‘s buffer. The READD
command reads back the programmed data EEPROM.
Alternatively, the programmer can perform the
verification once the entire device is programmed using
