input data/left, interface mode: AMS = ”Low”), or D1_SID is used as
right data serial data input pin and other pins are not used
input output (connect these to VDD) (when 1-bit serial interface
mode: AMS = ”High”).
- In common driver application mode, the data is
shifted
from
D2_DL(D4_DR)
to
D4_DR
(D2_DL),when in single type interface mode
(AMS = ”Low”). In dual-type application case, the
data are shifted from D2_DL and D3_DM (D4_DR
and D3_DM) to D4_DR(D2_DL). In each case the
direction of the data shift and the connection of data
pins are determined by SHL input (refer to NOTE3,
NOTE4).
When SHL = ”Low”, data is shifted from left to right.

When SHL = ”High”, the direction is reversed.(refer to VDD/VSS

- In segment driver application mode, the internal
operation is enabled only when enable input (ELB or
ERB) is “Low” (power down function). When several
drivers are serially connected, the enable state of each
driver is shifted according to the SHL input. Connect
these pins as below.
