A method for implementing a neural stimulation therapy mode in an implantable medical device (IMD) comprising the acts of mapping respective device states, defined by one or more timer states that include at least one neural event timer or one or more indications of one or more sensed physiologic events, to associated device actions in a stored neural table, storing an event represented as a device status word and a time stamp in a queue in response to an action input, and comparing one or more current timer states or one or more indications of one or more sensed physiologic events to a device state contained in the neural table and, if found to match, causing performance of one or more associated device actions, wherein the device actions include one or more of a neural stimulation energy delivery or a change in one or more timer states.
