Note 3: The data including the same consecutive data (three or more bytes) cannot be used as a password. (A password error

receiving PCSA; it does not receive password strings. In this case, the subsequent processing is performed correctly
because the TMP89FM82 keeps ignoring incoming data until the start mark (0x3A ":") in the Intel Hex format is detected,
even if the external controller transmits the dummy password string. However, if the dummy password string contains
"0x3A", it is detected as the start mark erroneously, and the microcontroller enters the halt mode. If this causes a problem,
do not transmit the dummy password strings.
