Family E Commands: Erase Fixed Length (Password Protected)
Command E0h—Erase Code Fixed Length
This command erases (programs to FFFFh) all words in a 256-word block of the program flash memory. The address given should be
located in the 256-word block to be erased. For example, providing address 0000h (in byte mode) to this command will erase the first
256-word block, address 0200h will erase the second block, and so on.
This command also combines the functionality of the “Load Code Variable Length” and “Verify Code Variable Length” commands.
Command E1h—Erase Data Fixed Length
This command erases a single word/byte in data SRAM to zero at (AddressH:AddressL).
