Appendix Standard Serial I/O Mode (Flash Memory Version)Mitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTERVersion Information Output CommandThis command outputs the version information of the control program stored in the boot area. Executethe version information output command as explained here following.(1) Send the “FB16” command code in the 1st byte of the transmission.(2) The version information will be output from the 2nd byte onward. This data is composed of 8ASCII code characters.CLK1RxD1(M16C reception data)FB16TxD1(M16C transmit data)'V' 'E' 'R''X'RTS1(BUSY)Figure 1.31.14.
