Instructions
Outline
Only the instruction register (IR) and the data register (DR) of the HD66726 can be controlled by the MPU.
Before starting internal operation of the HD66726, control information is temporarily stored in these
registers to allow interfacing with various peripheral control devices or MPUs which operate at different
speeds. The internal operation of the HD66726 is determined by signals sent from the MPU. These signals,
which include the register selection signal (RS), the read/write signal (R/W), and the data bus signal (DB0
to DB7), make up the HD66726 instructions. There are five categories of instructions that:
Control the display
Control power management
Set internal RAM addresses
Transfer data with the internal RAM
Control key scan (when serial interface mode)
Normally, instructions that perform data transfer with the internal RAM are used the most. However, auto-
incrementation by 1 (or auto-decrementation by 1) of internal HD66726 RAM addresses after each data
write can lighten the MPU program load.
Because instructions other than clear display instruction are executed in 0 cycle, instructions can be written
in succession.
While the clear display instruction is being executed for internal operation, or during reset, no instruction
other than the key scan read instruction can be executed.
