READY
According to configuration setting VD2, Bus Signal Translation translates MC68000 type MPU signals, or READY type
MPU signals to internal bus interface signals.
The Control Register contains 16 internal control and configuration registers. These registers can be accessed by either
direct-mapping or by using the built-in internal index register.
The Sequence Controller generates horizontal and vertical display timings according to the configuration registers settings.
The LCD Panel Interface performs frame rate modulation and output data pattern formatting for both passive monochrome
and passive color LCD panels.
