Family 4 Commands: Verify Variable Length (Password Protected)
Command 40h—Verify Code Variable Length
This command operates in the same manner as the “Load Code Variable Length” command, except that instead of programming the
input data into code flash, it verifies that the input data matches the data already in code space. If the data does not match, the sta-
tus code is set to reflect this failure.
Command 41h—Verify Data Variable Length
This command operates in the same manner as the “Load Data Variable Length” command, except that instead of writing the input
data into data SRAM, it verifies that the input data matches the data already in data space. If the data does not match, the status code
is set to reflect this failure.
Family 5 Commands: Load and Verify Variable Length (Password Protected)
Command 50h—Load and Verify Code Variable Length
This command combines the functionality of the “Load Code Variable Length” and “Verify Code Variable Length” commands.
Command 51h—Load and Verify Data Variable Length
This command combines the functionality of the “Load Data Variable Length” and “Verify Data Variable Length” commands.
Family 6 Commands: Erase Variable Length (Password Protected)
Command 60h—Erase Data Variable Length
This command has a slightly different format depending on the length of the erase requested. It clears (LengthL) or (LengthH:LengthL)
bytes/words in the data SRAM to zero starting at (AddressH:AddressL).
