14. The (m+2) th byte is a acknowledge response to the 27th to (m+1) th bytes.
15. If the (m+2) th byte was a normal acknowledge response, a branch is made to the
Next, the RAM Transfer routine performs the checksum operation to ensure data
integrity. Adding the series of the 19th to 25th bytes must result in 00H (with the carry
dropped). If it is not 00H, one or more bytes of data has been corrupted. In case of a
checksum error, the RAM Transfer routine sends back 0x11 to the controller and
returns to the state in which it waits for a command (i.e., the 3rd byte) again.

Transmit this checksum value from the controller to the target board. The checksum
calculation is described in details in a later section “Checksum Calculation”.
If there was a receive error, the RAM Transfer routine sends back 18H (bit 3) and
returns to the state in which it waits for a command (i.e., the 3rd byte) again. In this
case, the upper four bits of the acknowledge response are the same as those of the
previously issued command (i.e., all 1s). When the SIO0 is configured for I/O Interface
mode, the RAM Transfer routine does not check for a receive error.
Next, the RAM Transfer routine performs the checksum operation to ensure data
integrity. Adding the series of the 27th to (m+1) th bytes must result in 0x00 (with the
carry dropped). If it is not 0x00, one or more bytes of data has been corrupted. In case
of a checksum error, the RAM Transfer routine sends back 0x11 (bit 0) to the controller
and returns to the command wait state (i.e., the 3rd byte) again. When the above
checks have been successful, the RAM Transfer routine returns a normal
acknowledge response (0x10) to the controller.
• The RAM storage start address must be within the range of 0x2000_0400 to the
When the above checks have been successful, the RAM Transfer routine returns a
normal acknowledge response (0x10) to the controller.
