8-1-2. Busy flag
“1” of busy flag indicates that KS0108B is on the move and any instruction except
status read instruction can not be accepted the value of the busy flag is read out on
DB7 by the status read instruction make sure that the busy flag is reset(“0”) before
The issue of instruction.

8-1-3. Display on/off flip flop
Display on/off flip flop selects one of two states, on state and off state of segments, the
Display data corresponding to that in RAM is output to the segments. On the other hand,
The display data at all segments disappear in off state independent of ehte data in RAM.
It is controlled by display on/off instruction ”0” of RST signal sets the segments in off state,
The status of the flip flop is output to DB5 by status read instruction. Display on/off
Instruction does not inflence data in RAM.
