• Busy
When busy is 1, the LSI is executing internal operations. No instructions 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 conditions: 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 is being initialized. In this condition, no instructions except status
read can be accepted.
RESET = 0 shows that initializing has finished and the system is in the usual operation condition.
