Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

5.10.2Instruction Register and Supported Instructions

The instruction register is a 4-bit register that enacts the boundary scan instructions. After the state machine resets, the default instruction is IDCODE. The decode logic in the TAP controller selects the appropriate data register and configures the boundary scan cells for the current instruction.

Table 38 shows the supported boundary-scan instructions.
