ISP Commands
The following commands are accepted by the ISP command handler. Detailed return codes are supported for each command.
The command handler sends the return code INVALID_COMMAND when an undefined command is received. Commands and
return codes are in ASCII format.
CMD_SUCCESS is sent by ISP command handler only when received ISP command has been completely executed and the
new ISP command can be given by the host. Exceptions from this rule are "Set Baud Rate", "Write to RAM", "Read Memory",
and "Go" commands.
