 * new cmd/status channels on IPOD_AP added
 *
 * Revision 1.45  2007/10/22 15:23:28  trubac
 * Safer events scheduling, first copies data then signal new event.
 * Improved synchronous tasks events exchange
 *
 * Revision 1.44  2007/09/26 15:08:07  dellorto
 * dsp hf event replaced with hf event (generated by check hf fsm)
 *
