1. Normal operation. Interface is operating normally, with LPS
2. LPS deasserted. The LLC deasserts the LPS signal and, within
Philips Semiconductors
The sequence of events for resetting the PHY-LLC interface when it
is in the differentiated mode of operation (ISO terminal is low) is as
follows:

2-port/1-port 400 Mbps physical layer interface
active, SYSCLK active, status and packet data reception and
transmission via the CTL and D lines, and request activity via
the LREQ line.
1.0 ms, terminates any request or interface bus activity, and
places its LREQ, CTL, and D outputs into a high-impedance
state (the LLC should terminate any output signal activity such
that signals end in a logic 0 state).

may again assert LPS active. (The minimum T
provides sufficient time for the biasing networks used in Annex J
type isolation barrier circuits to stabilize and reach a quiescent
state if the isolation barrier has somehow become unbalanced.)
When LPS is asserted, the interface will be initialized as
