Table 29. Recommended JTAG Termination
Table 30. Supported Boundary Scan Instructions
TAP State Machine
The TAP pins drive a TAP controller, which implements the 16-state machine specified by the
IEEE 1149.1 specification. Following power up, the TAP controller must be reset by one of
following two mechanisms:
This ensures that the boundary scan cells do not block the pin to core connections in theIXF1110
MAC.
Instruction 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. The
table below shows the supported boundary scan instructions.
ID Register
The ID register is a 32-bit register. The IDCODE instruction connects this register between TDI
and TDO. Refer
descriptions.

interface is disabled. If the boundary scan logic is used, TRST_L must be pulsed Low after power-up to
ensure reset of the TAP controller. For more information, refer to
page 93
Asynchronous reset – achieved by pulsing or holding TRST_L low
Synchronous reset – achieved by clocking TCK with five clock pulses while TMS is held or
floats High.
