Instruction description
Outline
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:
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.
When an MPU program with checking the busy flag (DB7) is made, it must be necessary 1/2 fuss for executing
the next instruction by the falling edge of the “E” signal after the busy flag (DB7) goes to “LOW”.
