Analog GND.
Analog power supply.
Digital GND.
Digital power supply.
GND for driver output.
Open.
This pin is not connected with the
internal circuits.
Clock input.
Driver operation is synchronized with
this clock.
Reset input.
The IC is initialized by inputting low
level. However, the memory is not
initialized. Input high level during
normal operation.
Output mode switching.
Upper/Lower mode for low level input.
Upper/Lower/RGB mode for high level
input. (See the Description of Operation.)
Address input.
These pins are used to input the internal
RAM (luminance data, brightness data
and drive current data RAM) address.
RAM selection.
The luminance data RAM is selected
when this pin is low, and the drive
current data RAM when high.
Data I/O.
These pins are used to input and
output data to and from the internal
RAM (luminance data, brightness data
and drive current data RAM). See
Table 1. Read/Write Switching
Condition Correspondence Table for
the data I/O switching conditions.
