Table 15. JTAG Boundary-Scan Register
Note: The direction of shifting is from TDI to cell 104 to cell 103 . . . to cell 0 of TDO.
* Please refer to Pin Multiplexing in Section 4.1 for a description of pin multiplexing of BIO, PHIF, VEC[3:0], and SIO2.
† Note that shifting a zero into this cell in the mode to scan a zero into the chip will disable the processor clocks just as the STOP pin will.
‡ When the JTAG SAMPLE instruction is used, this cell will have a logic one regardless of the state of the pin.
