code for the Show Product Information command is 0x40.
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.
Enable command code (0x54).
If the 3rd byte is equal to any of the command codes listed in Table 20-4, 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 0x40. If the 3rd byte
is not a valid command, the boot program sends back 0xN1 (bit 0) to the controller and
returns to the state in which it waits for a command (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.
response to the 5th 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 0xN8 (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.
If the 5th byte is equal to any of the command codes to enable erasing, 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 0x54 and then
branches to the Chip Erase routine. If the 5th byte is not a valid command, the boot
program sends back 0xN1 (bit 0) to the controller and returns to the state in which it
waits for a command (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.
