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