Normal operation mode in which the module can receive graphic data and commands via the parallel
interface with high-speed data writing. High-speed graphic display is possible using this mode.
This mode is used for saving Memory-SW and various data to FROM.
Mode for re-writing firmware and built-in font data. Do not use unless necessary.
Test for display and internal operation. Used for factory test.
At power-on, the various display settings are set to default value, or value stored in Memory SW (refer
