DESCRIPTION
P18
I Serial/Parallel Select Input (Host Mode Only)
This pin is used in the Host mode to select between the parallel microprocessor
or serial interface. By default, the Host mode operates in the parallel micropro-
cessor mode. To configure the device for a serial interface, this pin must be
pulled "HIgh".
NOTE: Internally pulled “Low” with a 50kΩ resistor.
T13
I Serial Clock Input (Host Mode Only)
If Pin SER_PAR is pulled "High", this input pin is used the timing reference for
the serial microprocessor interface. See the Microprocessor Section of this
datasheet for details.
C10
I Serial Data Input (Host Mode Only)
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.
R7
O Serial Data Output (Host Mode Only)
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.
