Table 9-1 JTAG BOUNDARY SCAN REGISTER
BOUNDARY SCAN REGISTER
The boundary scan register is a required set of serial-shiftable register cells, formed by
connecting boundary scan cells placed at the device’s signal pins into a shift register path. The
VDD, VSS, and JTAG pins are NOT in the boundary-scan chain. The input to the shift
register is TDI and the output from the shift register is TDO. There are 4 different types of
boundary scan cells, based on the function of each signal pin.
The boundary scan register cells are dedicated logic and do not have any system function.
Data may be loaded into the boundary-scan register master cells from the device input pins
and output pin-drivers in parallel by the mandatory SAMPLE and EXTEST instructions.
Parallel loading takes place on the rising edge of TCK.
