This is the parallel data input/serial data input switch terminal.
P/S = HIGH: Parallel data input.
P/S = LOW: Serial data input.
The following applies depending on the P/S status:
When P/S = LOW, D0 to D5 are HZ. D0 to D5 may be HIGH, LOW or Open.
RD(E) and WR(R/W) are fixed to either HIGH or LOW.
With serial data input, RAM display data reading is not supported.
This is the MPU interface switch terminal.
C86=HIGH: 6800 Series MPU interface.
C86=LOW: 8080 MPU interface.
This is multi-level power supply for liquid crystal drive.
Voltage levels are determined based on VDD, and must maintain the relative
magnitudes shown below.
VDD (=V0)
Master operation When the power supply turns ON, the internal power supply
circuits produce V1 to V4 voltages shown below. The voltage setting are
selected using the LCD bias set command.
For 1/7 bias: V1=(1/7)xV5, V2=(2/7)xV5, V3=(5/7)xV5, V4=(6/7)xV5.
DC/DC voltage converter. Connects a capacitor between this terminal and C2–
terminal.
DC/DC voltage converter. Connects a capacitor between this terminal and C2+
terminal.
DC/DC voltage converter. Connects a capacitor between this terminal and C1+
terminal.
DC/DC voltage converter. Connects a capacitor between this terminal and C1–
terminal.
DC/DC voltage converter. Connects a capacitor between this terminal and C1+
terminal.
power supply for the step-up voltage circuit for the liquid crystal drive.
DC/DC voltage converter. Connects a capacitor between this terminal and VSS.
