LSEL

This is an input pin to select 1P Operation or 1/2P Operation. That can cope with different LCD

having different response time.

When LSEL is set at “L” level, 1P Normal Operation is selected. When LSEl is set at “H” level,

1/2P Operation is selected.

CSEL

This is a chip select signal input. When only one common driver is used, CSEL should be set at

“L” level. When multiple common drivers are used, CSEL of the leading chip must be tied to “L”

level and that of other chips must be tied to “H” level.

TEST1

This is a reserved pin and it must be set at “L” level in the normal operation.

TEST2

This is a reserved pin and it must be set at “L” level in the normal operation.

COM0 – COM239

These are output pins and provide common driving signals to the LCD panel. Output transition

occurs at the falling edge of LP.

Note 1 : If an MLA LCD system is formed by SSD1882 row driver, MLA column driver and MLA power chip, 1nF capacitors are

necessary for capacitor coupling between SSD1882 and MLA column driver signals. Refer to the Application Examples for

circuit connection.
