from the dedicated flash programmer, and the V850/SA1 performs the various processing corresponding to the
commands.
The following shows the response commands the V850/SA1 sends out.
16.6.5 Resources used
RAM and all the registers. The FFE800H to FFEFFFH area of the internal RAM retains data as long as the power is
on. The registers that are initialized by reset are changed to the default values.
