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".
N
Serial Clock Input (Host Mode Only)
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.
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.
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.
Analog JTAG Positive Pin
Analog JTAG Negative Pin
Test Data Out
This pin is used as the output data pin for the boundary scan chain.
Test Data In
This pin is used as the input data pin for the boundary scan chain.
Test Clock Input
This pin is used as the input clock source for the boundary scan chain.
Test Mode Select
This pin is used as the input mode select for the boundary scan chain.
Factory Test Pin
Transmitter Analog Ground
It’s recommended that all ground pins of this device be tied together.
OTE
: Internally pulled “Low” with a 50k resistor.
