The READP command instructs the programming
executive to read N 24-bit words of code memory
starting
Addr_MSB and Addr_LS. This command can only be
used to read 24-bit data. All data returned in response
to this command uses the packed data format
described in
Expected Response (2 + 3 * N/2 words for N even):

The PROGD command instructs the programming
executive to program one row of data EEPROM. The
data to be programmed is specified by the 16 data
words (D_1, D_2,..., D_16) and is programmed to the
destination address specified by Addr_MSB and
Addr_LSB. The destination address should be a
multiple of 0x20.
Once the row of data EEPROM has been programmed,
the programming executive verifies the programmed
data against the data in the command.
