26.4.5 Communication commands
The V850ES/KE1+ communicates with the dedicated flash programmer by means of commands. The signals sent
from the dedicated flash programmer to the V850ES/KE1+ are called “commands”. The response signals sent from
the V850ES/KE1+ to the dedicated flash programmer are called “response commands”.
