The Jam Player provides an interface for manipulating the IEEE
Std. 1149.1 JTAG TAP state machine. The TAP controller is a 16-state state
machine that is clocked on the rising edge of TCK, and uses the TMS pin to
control JTAG operation in a device. Figure 11–24 shows the flow of an
IEEE Std. 1149.1 TAP controller state machine.
