(2) send the operating frequency select command (3fh) to change the bit rate for communication. when the bit rate is set successfully, the mcu sends a response (06h). when the bit rate cannot be changed, or when the mcu fails to receive, the mcu sends an error response (bfh). (3) when the mcu receives a response (06h), the mcu waits for 1 - bit period at the bit rate for sending the operating frequency select command, and then set the bit rate of the programmer to the changed value. after that, the mcu sends communication confirmation data (06h) at the changed bit rate. when the mcu receives the command successfully, the mcu sends a response (06h) of the communication confirmation data. after correction (1) send the device select command (10h) to select the device to connect with the programmer and the endian of data that is programmed. when the program data is little endian, select the same device code as that for little endian in the response to the support device inquiry command. when the program data is big endian, select the same device code as that for big endian in the response to the support device inquiry command. when the device is selected successfully, the mcu sends a response ( 46h ). when the mcu fails to receive, the mcu sends an error response (90h). (2) send the operating frequency select command (3fh) to change the bit rate for communication. when the bit rate is set successfully, the mcu sends a response (06h). when the bit rate cannot be changed, or when the mcu fails to receive, the mcu sends an error response (bfh). (3) when the programmer receives a response (06h), the mcu waits for 1 - bit period at the bit rate for sending the operating frequency select command, and then set the bit rate of the programmer to the changed value. after that, the mcu sends communication confirmation data (06h) at the changed bit rate. when the mcu receives the command successfully, the mcu sends a response (06h) of the communication confirmation data.

a/e date : april 3, 2014 page 8 of 10 page 113 8 of 120 9 descriptions in 35.9.10.6 , erase ready operation are corrected as follows: before correct ion (1) send the erase preparation command (48h) to place the mcu in the erase wait state. the mcu enters the erase wait state and sends a response (06h). (2) send a block erase command (59h) to erase blocks in the mcu. when blocks are erased successfully, the mcu sends a response (06h). when the mcu fails to receive, the mcu sends an error response (d9h). send a block erase command repeatedly until block erase commands for all blocks are sent. when the operation ends before all the block erase commands are sent, a command error may occur even when a correct command is sent in the program/erase state. (3) in order to place the mcu in the program/erase state, send a block erase command for end of erase (59h 04h ffh ffh ffh ffh a7h). the mcu enters the program/erase state and sends a response (06h). after correction (1) send the erase preparation command (48h) to place the mcu in the erase wait state. the mcu enters the erase wait state and sends a response (06h). (2) send a block erase command (59h) to erase blocks in the mcu. when blocks are erased successfully, the mcu sends a response (06h). when the mcu fails to receive, the mcu sends an error response (d9h). send block erase commands repeatedly until a block erase command has been sent for the total numb er of blocks. the total number of blocks is the sum of the user area blocks and data area blocks that are obtained in advance using the block information inquiry command. if the operation ends before all the block erase commands are sent, a command error may occur even when a correct command is sent in the program/erase state. (3) send a block erase command for end of erase (59h 04h ffh ffh ffh ffh a7h). the mcu sends a response (06h). (4) to confirm whether erase ready operation has ended, send a boot mode status inquiry command (4fh). when the erase ready operation has ended, the mcu returns the result of the boot mode status inquiry. when the erase ready operation has not ended, th e mcu sends an error response (80h 4fh). when an error response is receiv ed, restart the mcu in boot mode and perform the procedure again from section 35.9.10.1 , bit rate automatic adjustment procedure .
