(see tap controller block diagram .) test data-out (tdo) the tdo output ball is used to serially clock data out from the registers. the output is active depending upon the current state of the tap state machine. the output changes on the falling edge of tck. tdo is con nected to the least significant bit (lsb) of any register. (see tap controller state diagram .) tap controller block diagram performing a tap reset a reset is performed by forcing tms high (v dd ) for five rising edges of tck. this reset does not affect the operation of the sram and may be performed while the sram is operating. at power up, the tap is reset internally to ensure that tdo comes up in a high-z state. tap registers registers are connected between the tdi and tdo balls and allow data to be scanned into and out of the sram test circuitry. only one register can be selected at a time through the instruction register. data is serially loaded into the tdi ball on the rising edge of tck. data is output on the tdo ball on the falling edge of tck. test-logic reset run-test/ idle select dr-scan select ir-scan capture-dr shift-dr capture-ir shift-ir exit1-dr pause-dr exit1-ir pause-ir exit2-dr update-dr exit2-ir update-ir 1 1 1 0 1 1 0 0 1 1 1 0 0 0 0 0 0 0 0 0 1 0 1 1 0 1 0 1 1 1 1 0 bypass register 0 instruction register 0 1 2 identi?cation register 0 1 2 29 30 31 . . . boundary scan register 0 1 2 . . x . . . s election circuitr y selection circuitry tck tms tap controller tdi tdo [+] feedback [+] feedback

pattern to allow for fault isolation of the board-level serial test data path. bypass register to save time when serially shifting data through registers, it is sometimes advantageous to skip certain chips. the bypass register is a single-bit register that can be placed between the tdi and tdo balls. this allows data to be shifted through the sram with minimal delay. the bypass register is set low (v ss ) when the bypass instruction is executed. boundary scan register the boundary scan register is connected to all the input and bidirectional balls on the sram. the boundary scan register is loaded with the contents of the ram input and output ring when the tap controller is in the capture-dr state and is then placed between the tdi and tdo balls when the controller is moved to the shift-dr state. the extest, sample/preload, and sample z instructions can be used to ca pture the contents of the input and output ring. the boundary scan order tables show the order in which the bits are connected. each bit corresponds to one of the bumps on the sram package. the msb of the register is connected to tdi, and the lsb is connected to tdo. identification (id) register the id register is loaded with a vendor specific, 32-bit code during the capture-dr state when the idcode command is loaded in the instruction regi ster. the idcode is hardwired into the sram and can be shifted out when the tap controller is in the shift-dr state. the id register has a vendor code and other information described in the identification register definitions on page 15 . tap instruction set overview eight different instructions ar e possible with the three bit instruction register. all combinations are listed in identification codes on page 15 . three of these instructions are listed as reserved and should not be used. the other five instructions are described in detail below. instructions are loaded into the tap controller during the shift-ir state when the instruct ion register is placed between tdi and tdo. during this state, instructions are shifted through the instruction register through the tdi and tdo balls. to execute the instruction once it is shifted in, the tap controller needs to be moved into the update-ir state. extest the extest instruction enables the preloaded data to be driven out through the system out put pins. this instruction also selects the boundary scan register to be connected for serial access between the tdi and tdo in the shift-dr controller state. idcode the idcode instruction causes a vendor specific 32-bit code to be loaded into the instruction register. it also places the instruction register between the tdi and tdo balls and allows the idcode to be shifted out of the device when the tap controller enters the shift-dr state. the idcode instruction is loaded into the instruction register upon power up or whenever the tap controller is given a test logic reset state. sample z the sample z instruction caus es the boundary scan register to be connected between the tdi and tdo balls when the tap controller is in a shift-dr state. the sample z command places all sram outputs into a high-z state. sample/preload sample/preload is a 1149.1 mandatory instruction. when the sample/preload instructions are loaded into the instruction register and the tap controller is in the capture-dr state, a snapshot of data on the input and output pins is captured in the boundary scan register. the user must be aware that the tap controller clock can only operate at a frequency up to 20 mhz, while the sram clock operates more than an order of magnitude faster. as there is a large difference in the clock frequencies, it is possible that during the capture-dr state, an input or output will undergo a transition. the tap may then try to capture a signal while in transition (metastable state). this will not harm the device, but there is no guarantee as to the value that will be captured. repeatable results may not be possible. to guarantee that the boundary scan register will capture the correct value of a signal, the sram signal must be stabilized long enough to meet the tap controller's capture setup plus hold times (t cs and t ch ). the sram clock input might not be captured correctly if there is no way in a design to stop (or slow) the clock during a sample/preload instruction. if this is an issue, it is still possible to capture all other signals and simply ignore the value of the ck and ck captured in the boundary scan register. once the data is captured, it is possible to shift out the data by putting the tap into the shift-dr state. this places the boundary scan register between the tdi and tdo pins. preload allows an initial data pattern to be placed at the latched parallel outputs of the boundary scan register cells pri- or to the selection of anothe r boundary scan test operation.
