Notes 
J1 1149.6 
IEEE 1149.1 test bus 
access to 1149.6 features 
U1 is the first device in the scan chain; U2 is the last device in 
the scan chain. TDO, TMS, TCK, /TRST (out) are from the test 
system to the device/chain under test. TDI (in) is from the 
device/chain under test to the test system. 
S1 
Short C1 
Up position to short coupling capacitor. 
S2 
Short C2 
Up position to short coupling capacitor. 
S3 
Open 
Down position to create open circuit. 
S4 
Open 
Down position to create open circuit at termination resistor. 
S5 
Open Termination Resistor 
Down position to create open circuit.
