JTAG SUPPORT
IEEE-1149.1. This standard specifies a design-for-testability technique called
Boundary-Scan test (BST). The operation of the boundary-scan circuitry is
controlled by an external test access port (TAP) Controller.
TEST ACCESS PORT (TAP)

data into or out of the Boundary-Scan register cells concurrently with the
operation of the device and without interfering with the on-chip logic.

TMS input. Both registers are described in a subsequent section. The received
input data is sampled at the rising edge of TCK pulses. This pin is internally pulled

of either the instruction register or data register are serially shifted out through
the TDO pin on the falling edge of each TCK pulse. When no data is shifted
through the boundary scan cells, the TDO driver is set to a High-Impedance
state.

INSTRUCTION REGISTER
instructions. The IDT72V73273 JTAG interface contains a four-bit instruction
register. Instructions are serially loaded into the instruction register from the TDI
when the TAP Controller is in its shift-IR state. Subsequently, the instructions are
decoded to achieve two basic functions: to select the test data register that may
operate while the instruction is current, and to define the serial test data register
path, which is used to shift data between TDI and TDO during data register
scanning. See Table 12 for Instruction decoding.
