21.BOUNDARY SCAN JTAG
The CS5376A includes an IEEE 1149.1 boundary scan JTAG port to test PCB interconnections. Refer to
the IEEE 1149.1 specification for more information about boundary scan testing.
21.1 Pin Descriptions
TRST - Pin 1
Reset input for the test access port (TAP) controller and all boundary scan cells, active low. Connect to
GND to disable the JTAG port.
TMS - Pin 2
Serial input to select the JTAG test mode.
TCK - Pin 3
Clock input to the TAP controller.
TDI - Pin 4
Serial input to the scan chain or TAP controller.
TDO - Pin 5
Serial output from the scan chain or TAP controller.
21.2 JTAG Architecture
The JTAG test circuitry consists of a test access port (TAP) controller and boundary scan cells connected
to each pin. The boundary scan cells are linked together to create a scan chain around the CS5376A.
