What is the assembly code to verify the signature bytes? Erik Malund said:
none this is ICP/parallel programming instructions Charles Townsend said:

Charles can u give me signature byte routine in assembly.
Please remember, this works for the EZ52 board in the above URL. My adaptation of the C code here. This routine reads 3 signature bytes and prints the bytes to the terminal. I am sure you can figure out the serial routines. And note that the EZ52 board in the above URL is a parallel programmer! As Erik said, it is not possible for the chip to read its own signature bytes - this code and schematic relate to a separate processor reading the signature from another processor...! |
