Multi-level power used to drive LCDs. Voltage specified to each LCD cell is divided by
resistors or impedance-converted by an operational amplifier before being applied. Each
voltage to be applied must be based on V

3.2.2 System Bus Interface Signals
D

–D
0
8–bit, tri-state, bi-directional I/O bus. Normally, connected to the data bus of an 8–/16–
bit standard microcomputer.
A0
Input pin. Normally, the LSB of the MPU address bus is connected to this input pin to
provide data/command selection.
0: Display control data on D

RES
Input pin. The SED1520 can be reset or initialized by setting RES to low level (if it is
interfaced with a 68 family MPU) or high level (if with an 80 family MPU). This reset op-
eration occurs when an edge of the RES signal is sensed. The level input selects the
type of interface with the 68 or 80 family MPU:
High level: Interface with 68 family MPU
Low level:
Interface with 80 family MPU
