9.1 Asynchronous Signal Recovery
Phys may support asynchronous signal recovery for those applications where the usage model of device insertion into a receptacle does not apply. When
signal is lost, both the host and the device may attempt to recover the signal. A host or device shall determine loss of signal as represented by a transition
from PHYRDY to PHYRDYn, which is associated with entry into states LSI: NoCommErr or LS2:NoComm within the Link layer. Note that negation of
PHYRDY does not always constitute a loss of signal. Recovery of the signal is associated with exit from state LS2:NoComm. If the device attempts to
recover the signal before the host by issuing a COMINIT, the device shall return its signature following completion of the OOB sequence which included
COMINIT. If a host supports asynchronous signal recovery, when the host receives an unsolicited COMINIT, the host shall issue a COMRESET to the
device. When a COMRESET is sent to the device in response to an unsolicited COMINIT, the host shall set the Status register to 7Fh and shall set all
other Shadow Command Block Registers to FFh. When the COMINIT is received in response to the COMRESET which is associated with entry into state
HP2B:HR_AwaitNoCOMINIT, the Shadow Status register value shall be updated to either FFh or 80h to reflect that a device is attached.
