11.Instruction description
11.1Outline
To overcome the speed difference between the internal clock of KS0066U and the MPU clock, KS0066U
performs internal operations by storing control in formations to IR or DR. The internal operation is determined
according to the signal from MPU, composed of read/write and data bus (Refer to Table7).
Instructions can be divided largely into four groups:
1) KS0066U function set instructions (set display methods, set data length, etc.)
2) Address set instructions to internal RAM
3) Data transfer instructions with internal RAM
4) Others
The address of the internal RAM is automatically increased or decreased by 1.
Note: during internal operation, busy flag (DB7) is read “High”.
Busy flag check must be preceded by the next instruction.
