The Received bitstream viewer enables a bit-by-bit analysis of the test responses obtained from the execution of a given test program. This utility displays the sequence of 0/1/Z values captured at the RX (TDO) parallel port pins (for TAP0 and TAP1), as shown in figure 1 below.

Due to the very low level of detail enabled by this utility, a colouring function is available to facilitate the identification of the bitstream segments to be analysed.
