PI7C7100
3-Port PCI Bridge
ADVANCE INFORMATION
The instruction determines the test to be performed, the test data register to be accessed, or both. The IR is two bits wide.
When the IR is selected, the most significant bit is connected to TDI, and the least significant bit is connected to TDO.
The value presented on the TDI pin is shifted into the IR on each rising edge of TCK. The TAP controller captures fixed
parallel data (01 binary ). When a new instruction is shifted in through TDI, the value 01 (binary) is always shifted out through
TDO, least significant bit first. This helps identify instructions in a long chain of serial data from several devices.
Upon activation of the TRST# reset pin, the latched instruction asynchronously changes to the idcode instruction. When
the TAP controller moves into the test state other than by reset activation, the opcode changes as TDI shifts, and becomes
active on the falling edge of TCK.
15.2 Boundary-Scan Instruction Set
The PI7C7100 supports three mandatory boundary-scan instructions (bypass, sample/preload and extest). The table
shown below lists the PI7C7100s boundary-scan instruction codes. The reserved code should not be used.
