Length+8

Input (to dump

256+ units)

20h 2 AddrL AddrH LenL LenH 00h 00h... 00h

Output

Memory

contents

03Eh

This command has a slightly different format depending on the length of the dump requested. It returns the

contents of the program flash memory – (Length) or (LenH:LenL) bytes starting at byte address (AddrH:AddrL).

“Units” is either bytes or words, depending on which mode is currently selected.
