byte data from the address specified by the password comparison start address. The external control-
ler should send N-byte password data to the device. If the passwords do not match, the device enters
the halt condition without returning an error code to the external controller. If the addresses from
FFFE0H to FFFFFH are filled with “FFH”, the passwords are not conpared because the device is con-
sidered as a blank product.
mat. No received data is echoed back to the external controller. After receiving the start mark (3AH
for “:”) in the Intel Hex format, the device starts data record reception. Therefore, the received data
except 3AH is ignored until the start mark is received. After receiving the start mark, the device
receives the data record, that consists of data length, address, record type, write data and checksum.
Since the device starts checksum calculation after receiving an end record, the external controller
should wait for the checksum after sending the end record. If a receiving error or Intel Hex format
error occurs, the device enters the halts condition without returning an error code to the external con-
troller.
late the SUM, refer to " 19.8 Checksum (SUM) ". The checksum is calculated only when the end
record is detected and no receiving error or Intel Hex format error occurs. After sending the end
record, the external controller judges whether the transmission is completed correctly by receiving the
checksum sent by the device.
