Fixed-Point Digital Signal Processor

SPRS166H – APRIL 2001 – REVISED NOVEMBER 2004

The TMS320VC5502 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.

BSDL models are available on the web in the TMS320VC5502 product folder under the “simulation

models” section.
