18 Flash Memory Operation
2)
Show Flash Memory Sum Command (See Table 18-7)
1. The processing of the 1st and 2nd bytes are the same as for the RAM Transfer
2. The 3rd byte, which the target board receives from the controller, is a command. The
3. The 4th byte, transmitted from the target board to the controller, is an acknowledge
4. The Show Flash Memory Sum routine adds all the bytes of the flash memory together.
5. The 7th byte is a checksum value for the 5th and 6th bytes. To calculate the checksum
6. The 8th byte is the next command code.
command.
code for the Show Flash Memory Sum command is 20H.
response to the 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 (bit 3) and returns to the command wait state 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 18-4, 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 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 (bit 0) to the controller and returns to the
command wait state (the third byte) 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.
The 5th and 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 a later section “Calculation of the Show Flash Memory Sum Command”.
value, add 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.
