Instructions
Outline
The HD66750/1 uses the 16-bit bus architecture. Before the internal operation of the HD66750/1 starts,
control information is temporarily stored in the registers described below to allow high-speed interfacing
with a high-performance microcomputer. The internal operation of the HD66750/1 is determined by
signals sent from the microcomputer. These signals, which include the register selection signal (RS), the
read/write signal (R/W), and the data bus signals (DB15 to DB7), make up the HD66750/1 instructions.
There are seven categories of instructions that:
Specify the index
Read the status
Control the display
Control power management
Process the graphics data
Set internal CGRAM addresses
Transfer data to and from the internal CGRAM
Normally, instructions that write data are used the most. However, an auto-update of internal CGRAM
addresses after each data write can lighten the microcomputer program load.
Because instructions are executed in 0 cycles, they can be written in succession.
