ta (N) stored in the password count storage address. The external password data is compared with
N-byte data from the address specified by the password comparison start address. The external con-
troller should send N-byte password data to the device. If the passwords do not match, the device en-
ters the halt condition without returning an error code to the external controller. If the addresses
from FFE0H to FFFFH are filled with “FFH”, the passwords are not compared because the device
is considered 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 re-
ceived 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 controller.
late the SUM, refer to "15.8 Checksum (SUM)". The checksum is calculated only when the end re-
cord is detected and no receiving error or Intel Hex format error occurs. After sending the end re-
cord, the external controller judges whether the transmission is completed correctly by receiving
the checksum sent by the device.
