SPI (SERIAL PERIPHERAL INTERFACE)
N
OTE
:
These pins are only used if the SPI interface is used in place of the parallel microprocessor interface. The SPI
Microprocessor interface uses shared pins except for SER/PAR.

Serial/Parallel Select Input
This pin is used to select between the parallel microprocessor or serial inter-
face. By default, the parallel microprocessor mode is selected. To configure
the device for a serial interface, this pin must be pulled "HIgh".
N
OTE
:
Internally pulled “Low” with a 50k
resistor.
SCLK/PCLK

I
Serial Clock Input
If Pin SER_PAR is pulled "High", this input pin is used as the timing reference
for the serial microprocessor interface. See the Microprocessor Section of this
datasheet for details.
SDI/ADDR0
T15
I
Serial Data Input
If Pin SER_PAR is pulled "High", this input pin from the serial interface is used
to input the serial data for Read and Write operations. See the Microprocessor
Section of this datasheet for details.
SDO/D0
Y5
O
Serial Data Output
If Pin SER_PAR is pulled "High", this output pin from the serial interface is
used to read back the regsiter contents. See the Microprocessor Section of
this datasheet for details.
