is the data (N) indicated by the password count storage address. The password
data are compared for N entries beginning with the password comparison start
address. The controller should send N bytes of password data to the device. If the
passwords do not match, the device stops UART function without returning error
code to the controller. If the data of addresses from FFE0H to FFFFH are all
“FFH”, the comparison of passwords is not executed because the device is
considered as a blank product.
in Intel Hex format. No received data are echoed back to the controller. The data
which is not the start mark (3AH for “:”) in Intel Hex format is ignored and does
not send an error code to the controller until the device receives the start mark.
After receiving the start mark, the device receives the data record, that consists of
length of data, address, record type, writing data and checksum. After receiving
the checksum of data record, the device waits the start mark data (3AH) again.
The data of data record is temporarily stored to RAM and then, is written to
specified FLASH memory by page (128 bytes) writing. For details of an
organization of FLASH, refer to 2.18.7 “FLASH Memory Writing Data Format”.
Since after receiving an end record, the device starts to calculate the SUM, the
controller should wait the SUM after sending the end record. If receive error or
Intel Hex format error occurs, the device stops UART function without returning
error code to the controller.
order of the upper byte and the lower byte. For details on how to calculate the
SUM, refer to 2.18.9 “Checksum (SUM)”. The SUM calculation is performed after
detecting the end record, but the calculation is not executed when receive error or
Intel Hex format error has occurred. The time required to calculate the SUM of
the 48 Kbytes of FLASH memory area is approximately 150 ms at fc
After the SUM calculation, the device sends the SUM data to the controller. After
sending the end record, the controller can judge that the transmission has been
terminated correctly by receiving the checksum.
