Communication commands
The microcontroller communicates with the flash programmer via commands.
The commands sent to the microcontroller are called commands, and the
response signals sent by the microcontroller to the flash programmer are
called response commands.
Communication commands
The following table lists the flash memory control commands of the
microcontroller. All these commands are issued by the flash programmer, and
the microcontroller performs the corresponding processing.
