Functions
Data register or instruction register select input. Data register when "1" and instruction register when "0".
Read or write select input. Read when "1" and write when "0".
Execution start input
4-bit microcontroller interface data bus and 8-bit microcontroller interface high-order four bits data bus
connections. DB7 can also be used as busy flag.
8-bit microcontroller interface low-order four bits data bus connections. No connection when 4-bit interface
size is selected.
D serial data shift latch output
D serial data shift clock output
Display expansion drive signal inversion control signal output
Display expansion serial data output. Nonselected when "0" and selected when "1".
LCD common driver outputs. OC9 to OC16 and OC12 to OC16 are unselected in 1/8 duty and 1/11 duty
respectively.
LCD segment driver outputs
LCD driver reference voltage inputs
VDD : +5V, GND : 0V
Oscillator feedback resistor connection and external clock input
Oscillator external feedback resistor connection
Internal feedback resistor connection. Connect to OSCI or leave open.
Segment output shift direction select input. Shift right (OS1 to OS80) when"1", and shift left (OS80 to OS1)
when "0".
M output signal type select input. A-type when "1" and B-type when "0".
LCD drive voltage internal voltage divider outputs. Leave open if the the voltage divider is not used.
No. 4101—8/32
