During normal operation, host can simply send a WAKE or SLEEPtoACTIVE ping to the base device and the corresponding tone will be generated to the rest of the stack devices as seen in Figure 8-5. During system development, if there is a need to send WAKE or SLEEPtoACTIVE to only some of the devices in the daisy chain, host can use the CONTROL1[SEND_WAKE] or CONTROL1[SEND_SLPTOACT] bits. The SHUTDOWN and HW_RESET ping or tone are mostly used as a communication recovery attempt. Hence these pings/tones are non-propagable.
