(6) The 8th byte is the next command code.
(1) The processing of the 1st and 2nd bytes are the same as for the RAM Transfer command.
(2) The 3rd byte, which the target board receives from the controller, is a command. The code for the

received, the boot program echoes back a value of 20H and then branches to the Show Flash
Memory Sum routine.
If the 3rd byte is not a valid command, the boot program sends back x1H to the controller and
returns to the state in which it waits for a command again. In this case, the upper four bits of the
acknowledge response are undefined — they hold the same values as the upper four bits of the
previously issued command.
6th bytes, transmitted from the target board to the controller, indicate the upper and lower bytes of
this total sum, respectively. For details on sum calculation, see Section 3.5.14.
the 5th and 6th bytes together, drop the carry and take the two’s complement of the sum. Transmit
this checksum value from the controller to the target board.
Show Product Information command is 30H.
3rd byte. Before sending back the acknowledge response, the boot program checks for a receive
error. If there was a receive error, the boot program transmits x8H and returns to the state in which
it waits for a command again. In this case, the upper four bits of the acknowledge response are
undefined — they hold the same values as the upper four bits of the previously issued command.
When the SIO0 is configured for I/O Interface mode, the boot program does not check for a
receive error.
If the 3rd byte is equal to any of the command codes listed in Table 3.5 on page 33, the boot
program echoes it back to the controller. When the Show Flash Memory Sum command was
received, the boot program echoes back a value of 30H and then branches to the Show Flash
Memory Sum routine.
If the 3rd byte is not a valid command, the boot program sends back x1H to the controller and
returns to the state in which it waits for a command again. In this case, the upper four bits of the
acknowledge response are undefined — they hold the same values as the upper four bits of the
previously issued command.

possible by storing a software id in these locations.
