25.1.2 TAP Controller
The TAP controller interprets the sequence of logical values on the
TMS
signal. This synchronous
state machine controls the operation of the JTAG logic. The value adjacent to each arc in Figure
25-2 represents the value of the
TMS
signal sampled on the rising edge of the
TCK
signal. For a
description of the TAP controller states, refer to the IEEE Std. 1149.1 documentation.
