10.4 BOUNDARY SCAN REGISTER
10.5 JTAG BOUNDARY SCAN REGISTER ORDER
June 2009 – Revision 1.5
Pericom Semiconductor
The boundary scan register has a set of serial shift-register cells. A chain of boundary scan cells is formed by
connected the internal signal of the PI7C9X20508GP package pins. 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.
