14.2 BYPASS REGISTER
14.3 DEVICE ID REGISTER
14.4 BOUNDARY SCAN REGISTER
14.5 JTAG BOUNDARY SCAN REGISTER ORDER
PI7C9X110 implements a 5-bit Instruction register to control the operation of the JTAG logic. The defined
instruction codes are shown in Table 14-1. Those bit combinations that are not listed are equivalent to the BYPASS
(11111) instruction:
Table 14-1 Instruction register codes
The required bypass register (one-bit shift register) provides the shortest path between TDI and TDO when a bypass
instruction is in effect. This allows rapid movement of test data to and from other components on the board. This
path can be selected when no test operation is being performed on the PI7C9X110.
This register identifies Pericom as the manufacturer of the device and details the part number and revision number
for the device.
Table 14-2 JTAG device ID register
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 PI7C9X110 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.
