XRT83VSH316

16-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT

SPI (SERIAL PERIPHERAL INTERFACE)

NOTE: 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.

DESCRIPTION

SER/PAR

T17

I

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".

NOTE: Internally pulled “Low” with a 50k resistor.

SCLK/PCLK

U6

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.

DESCRIPTION

Analog Test Pin_TIP

Analog Test Pin_RING

These pins are used to check continuity of the Transmit and Receive TIP and

RING connections on the assembled board.

NOTE: See “Section 5.7, Analog Board Continuity Check” on page 48

for more detailed description.

Test Mode Select

This pin is used as the input mode select for the boundary scan chain.

NOTE: Internally pulled "High" with a 50K resistor.

Test Clock Input

This pin is used as the input clock source for the boundary scan chain.

NOTE: Internally pulled "High" with a 50K resistor.

Test Data In

This pin is used as the input data pin for the boundary scan chain.

NOTE: Internally pulled "High" with a 50K resistor.

Test Data Out

This pin is used as the output data pin for the boundary scan chain.
