Description
D0~D3
I
CMOS IN
Pull-high
or floating
Data inputs for the parallel mode
When the IC is operating in the serial mode, the data input
terminals (D0~D3) are included with a pull-high resistor. When
the IC is operating in the parallel mode, these pins become
floating.

CLK
I
CMOS IN
Pull-high
or floating
Data synchronous clock input for the serial mode
When the IC is operating in the parallel mode, the input
terminal (CLK ) is included with a pull-high resistor. When the
IC is operating in the serial mode, this pin becomes floating.
