FUNCTIONAL BLOCK DESCRIPTIONS
Command Decoder Command Interface
This module determines whether input data interpreted data command. Data directed this module based upon input pin. high, data written internal memories (DDRAM, CGRAM, ICONRAM). low, input D7-D0 interpreted Command will decoded written corresponding command register.
Parallel 6800-series Interface bits mode
parallel interface consists bi-directional data pins (D7-D0), input high indicates read operation from internal (DDRAM, CGRAM ICONRAM). input indicates write operation internal (DDRAM, CGRAM ICONRAM) Internal Command Registers depending status input. input serves data latch signal (clock) when high provided that low. Refer Figure Parallel Interface Timing Diagram 6800-series microprocessors. order match operating frequency display with that microprocessor, some pipeline processings internally performed which require insertion dummy read before first actual display data read. This shown Figure below. dummy read make address counter (AC) increased recommended address again before writing. consecutive read after dummy read also valid data. instruction read cycle supported regarded operation cycle.
