Output mode circuit type: open drain
Function after a power on reset: input port
Can be set up to function as output ports by bits I/O-1 to
I/O-3 in the serial data sent from the controller.
IThis pin must be set high to input serial data to the
LC72146 DI pin or to output serial data from the DO pin.
Inputs the clock used for data synchronization when
inputting serial data to the LC72146 DI pin or outputting
serial data from the DO pin.
Input pin for serial data transmitted to the LC72146 from
a controller.
Output pin for serial data transmitted from the LC72146 to
a controller.
The LC72146 power supply connection. A voltage
between 4.5 and 5.5 volts must be supplied when the
PLL circuit is used.
The power on reset circuit operates when power is first
applied.
