SAM-BA Monitor

Once the communication interface is identified, the monitor runs in an infinite loop, waiting for different commands, as shown in the following table.

Mode commands:
- Normal mode configures SAM-BA Monitor to send/receive data in binary format
- Terminal mode configures SAM-BA Monitor to send/receive data in ASCII format
Write commands: Write a byte (O), a halfword (H) or a word (W) to the target
- Address: Address in hexadecimal
- Value: Byte, halfword or word to write in hexadecimal
Read commands: Read a byte (o), a halfword (h) or a word (w) from the target
- Address: Address in hexadecimal
- Output: The byte, halfword or word read in hexadecimal
Send a file (S): Send a file to a specified address
- Address: Address in hexadecimal
  Note: There is a timeout on this command which is reached when the prompt ‘>’ appears before the end of the command execution.
Receive a file (R): Receive data into a file from a specified address
- Address: Address in hexadecimal
- NbOfBytes: Number of bytes in hexadecimal to receive
Go (G): Jump to a specified address and execute the code
- Address: Address to jump in hexadecimal
Get Version (V): Return the SAM-BA boot version
Note: In Terminal mode, when the requested command is performed, SAM-BA Monitor adds the following prompt sequence to its answer: <LF>+<CR>+'>'.
