21.2.3 Boundary Scan Cells

The CS5376A JTAG test port provides access to all

device pins via internal boundary scan cells. When

the JTAG port is disabled, boundary scan cells are

transparent and do not affect CS5376A operation.

When the JTAG port is enabled, boundary scan

cells can write and read each pin independent of

CS5376A operation.

Boundary scan cells are serially linked to create a

scan chain around the CS5376A controlled by the

TAP controller. Table 19 lists the scan cell map-

ping of the CS5376A.
