The TEMAP-84 supports the IEEE Boundary Scan Specification as described in

the IEEE 1149.1 standards. The Test Access Port (TAP) consists of the five

standard pins, TRSTB, TCK, TMS, TDI and TDO used to control the TAP

controller and the boundary scan registers. The TRSTB input is the active-low

reset signal used to reset the TAP controller. TCK is the test clock used to

sample data on input, TDI and to output data on output, TDO. The TMS input is

used to direct the TAP controller through its states. The basic boundary scan

architecture is shown below.
