CHAPTER 26 FLASH MEMORYUser’s Manual U16896EJ2V0UD64026.4.5 Communication commandsThe V850ES/KE1+ communicates with the dedicated flash programmer by means of commands. The signals sentfrom the dedicated flash programmer to the V850ES/KE1+ are called “commands”. The response signals sent fromthe V850ES/KE1+ to the dedicated flash programmer are called “response commands”.Figure 26-9. Communication CommandsDedicated flash programmer V850ES/KE1+CommandResponse commandPG-FP4(Flash Pro4)CxxxxxxBxxxxxAxxxxXXX YYYXXXXX XXXXXXXXXXXXXX YYYYSTATVEThe following shows the commands for flash memory control in the V850ES/KE1+. All of these commands areissued from the dedicated flash programmer, and the V850ES/KE1+ performs the processing corresponding to thecommands.Table 26-7.
