svf_add_statemove()

int svf_add_statemove

(

tap_state_t

goal_state

)

svf_add_statemove() moves from the current state to goal_state.

Parameters

goal_state

The final TAP state.

Returns

ERROR_OK on success, or an error code on failure.

The current and goal states must satisfy svf_tap_state_is_stable(). State transition paths used by this routine are those given in the SVF specification for single-argument STATE commands (and also used for various other state transitions).
