Function
In segment driver application mode, these pins are
used as 4-bit data input pin (when 4-bit parallel
interface mode : AMS = "Low"), or D1_SID is used as
serial data input pin and other pins are not used
(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 NOTE 3, NOTE 4).
When SHL = "Low", data is shifted from left to right.
When SHL = "High", the direction is reversed. (refer
to NOTE3)
– 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.
