•Busy
When busy is 1, the LSI is executing internal operations. No instruction are accepted
while busy is 1, so you should make sure that busy is 0 before writing the next
instruction.
•ON/OFF
Shows the liquid crystal display condition: on condition or off condition.
When on/off is 1, the display is in off condition.
When on/off is 0, the display is in on condition.
•RESET
RESET = 1 shows that the system system is being initialized. In this condition, no
instructions except status read can be accepted.
RESET = 0 shows that initializing has system is in the usual operation condition.
