For the following two commands, the Intel Hex format is used in part of the transfer format:
For information on the definition of the Intel Hex format, refer to Table 22-20.
Data is in binary form. The start mark ":" must be transmitted as binary data of 0x3A.
- Flash memory write command (0x30)
- RAM loader command (0x60)
1. After receiving the checksum of each data record, the TMP89FM42 goes into a wait state and awaits the

arrival of the start mark (0x3A ":") of the next data record. Although the external controller transmits data
other than 0x3A between records, the TMP89FM42 ignores such data when it is in this wait state.
into a wait state and does not transmit any data until the arrival of 3-byte data (overwrite detection, upper
and lower bytes of the checksum). (3-byte data is used if the flash memory write command is used. If the
RAM loader command is used, the external controller awaits the arrival of 2-byte data, or upper and lower
bytes of the checksum.)
ing an error code to the external controller. The Intel Hex format error occurs in the following cases:
- If the record type is other than 00h, 01h, or 02h
- If a checksum error of the Intel Hex format occurs
- If the data length of an extended record (record type = 0x02) is not 0x02
- If the TMP89FM42 receives the data record after receiving an extended record (record type = 0x02)
- I the data length of the end record (record type = 0x01) is not 0x00
- If the offset address of an extended record (record type = 0x02) is not 0x0000
whose segment address is more than 0x2000
