93 * These paths are from the SVF specification for the STATE command, to be
94 * used when the STATE command only includes the final state. The first
95 * element of the path is the "from" (current) state, and the last one is
96 * the "to" (target) state.
98 * All specified paths are the shortest ones in the JTAG spec, and are thus
99 * not (!!) exact matches for the paths used elsewhere in OpenOCD. Note
100 * that PAUSE-to-PAUSE transitions all go through UPDATE and then CAPTURE,
101 * which has specific effects on the various registers; they are not NOPs.
103 * Paths to RESET are disabled here. As elsewhere in OpenOCD, and in XSVF
104 * and many SVF implementations, we don't want to risk missing that state.
105 * To get to RESET, always we ignore the current state.
