6.34.5 JTAG 1149.1 Boundary Scan Considerations
To use boundary scan, the following sequence should be followed:
- Execute a valid reset sequence and exit reset
- Wait at least 6000 OSCIN clock cycles
- Enter boundary scan mode using the JTAG pins
No specific value is required on the EMU0 and EMU1 pins for boundary scan testing. If TRST is not driven by the boundary scan tool or tester, TRST should be externally pulled high during boundary scan testing.
