Notices Concerning JTAG (IEEE 1149.1) Boundary Scan Test Capability
4.1.1 Initialization Requirements for Boundary Scan Test
The TMS320VC5509A uses the JTAG port for boundary scan tests, emulation capability and factory test
purposes. To use boundary scan test, the EMU0 and EMU1/OFF pins must be held HIGH through a rising edge
of the TRST signal prior to the first scan. This operation selects the appropriate TAP control for boundary scan.
If at any time during a boundary scan test a rising edge of TRST occurs when EMU0 or EMU1/OFF are not
high, a factory test mode may be selected preventing boundary scan test from being completed. For this
reason, it is recommended that EMU0 and EMU1/OFF be pulled or driven high at all times during boundary
scan test.
4.1.2 Boundary Scan Description Language (BSDL) Model
BSDL models are available on the web in the TMS320VC5509A product folder under the “simulation models”
section.
