... NHD-0420AZ Read mode timing diagram Block diagram 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 DR. The internal operation is determined according to the signal from MPU, composed of read/write and data bus (Refer to Table7). ...

... NHD-0420AZ 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”. ...
