10. Test information
10.1 Boundary scan test
The SAA7134HL has built-in logic and five dedicated pins to support boundary scan
testing which allows board testing without special hardware (nails).
The SAA7134HL follows the IEEE Std. 1149.1 - Standard Test Access Port and Boundary
- Scan Architectureset by the Joint Test Action Group (JTAG) chaired by Philips.
The 5 special pins are: Test Mode Select (TMS), Test Clock (TCK), Test Reset (TRST_N),
Test Data Input (TDI) and Test Data Output (TDO).
The Boundary Scan Test (BST) functions BYPASS, EXTEST, SAMPLE, CLAMP and
IDCODE are all supported (see
Table 21
). Details about the JTAG BST-test can be found
in the specification IEEE Std. 1149.1 A file containing the detailed Boundary Scan
Description Language (BSDL) description of the SAA7134HL is available on request.
10.1.1
Initialization of boundary scan circuit
The Test Access Port (TAP) controller of an IC should be in the reset state
(TEST_LOGIC_RESET) when the IC is in the functional mode. This reset state also
forces the instruction register into a functional instruction such as IDCODE or BYPASS.
To solve the power-up reset, the standard specifies that the TAP controller will be forced
asynchronously to the TEST_LOGIC_RESET state by setting pin TRST_N to LOW-level.
10.1.2
Device identification codes
When the IDCODE instruction is loaded into the BST instruction register, the identification
register will be connected internally between pins TDI and TDO of the IC. The
identification register will load a component specific code during the
CAPTURE_DATA_REGISTER state of the TAP controller and this code can subsequently
be shifted out. At board level, this code can be used to verify component manufacturer,
