The READP command instructs the programming
executive to read N 24-bit words of code memory,
including Configuration registers, starting from the
24-bit address specified by Addr_MSB and Addr_LS.
The entire data returned in response to this command
uses
Section 5.2.2 “Packed Data Format”.
Expected Response (2 + 3 * N/2 words for N even):
Expected Response (4 + 3 * (N – 1)/2 words for N odd):

READP COMMAND
This command can only be used to read
24-bit data.
Reading unimplemented memory will
cause the programming executive to
reset. Ensure that only memory locations
present on a particular device are
accessed.

The PROGC command instructs the programming
executive to program a single User ID register located
at the specified memory address.
After the specified data word has been programmed to
code memory, the programming executive verifies the
programmed data against the data in the command.
Expected Response (2 words):
5.2.10
The PROGD command instructs the programming
executive to program one word (16-bit) of data
EEPROM memory, starting from the 24-bit address
specified by Addr_MSB and Addr_LS.
Once one word of data EEPROM has been
programmed, the programming executive verifies the
programmed data against the data in the command.
