JTAG Test Port
JTAG Test Port is a 4-pin interface consisting of:
TCK: Test Clock
TMS: Test Mode Select
TDI: Test Data Input
TDO: Test Data Output
To put the ADV7160/ADV7162 into the required mode, the In-
struction Register must be loaded.

The ADV7160 implementation has the mandatory instructions:
Bypass, Sample/Preload and Extest, and the optional instruc-
tion: IDCode. There is also one private instruction: Private1.
The Private1 instruction is for internal use in production test
only.
The IDCode is a 32-bit number which can be scanned out
through TDO. Its contents are defined below:

The Boundary Scan Chain is a fundamental feature of the
JTAG Test Port. It allows all the digital input and output pins
on the part to be connected into a shift register between the
TDI and TDO pins. The digital pins can be sampled, or con-
trolled over the JTAG port to carry out testing. The is no
boundary scan cell on the PLL
REF
pin. The Three-State Control
cell controls the three-state status of the microport databus.
There are 131 cells in total on the Boundary Scan Chain.
