INSTRUCTION DESCRIPTION

OUTLINE

To overcome the speed difference between the internal clock of S6A0072 and the MPU clock, the S6A0072

performs an internal operation by storing control information to IR or DR. The internal operation is determined

according to the signal from MPU, composed of read/write and data bus.

Instruction can be divided into four types:

• S6A0072 function set instructions (set display methods, set data length, etc.)

• Address set instructions to internal RAM

• Data transfer instructions with internal RAM

• Others.

The address of internal RAM is automatically increased or decreased by 1.

NOTE: During an internal operation, the busy flag (DB7) is high. Busy flag check must precede the next instruction.

When an MPU program with busy flag (DB7) checking is made, 1/2Fosc is necessary for executing the next

instruction by the falling edge of the "E" signal after the busy flag (DB7) goes to "Low".
