This register holds additional time-out values used at different states of the RX LSM. The actual
time represented by the timeout value in this register can be obtained as:
Real_time = Timeout_value * Internal_timer_tick_interval
Also, note that actual timeout period may be one less than the specified timeout interval, due to
the asynchronous nature of events with respect to the timer. For example, if the interval is 0.25
ns, and the timeout_value is specified as 4, then the timeout will occur after 0.75 ns to 1.00 ns in
that state. To guarantee a timeout of at least 1 second, a value of 0x5 would have to be written.
RX_link_deleted_timeout
In the case of link deletion, this value determines how long the RX LSM should stay in the
DELETED state before it can move to the UNASSIGNED state (if the FE does not report
TX != Active). The set_rx_phy_defect command immediately terminates this timer
(causing an immediate transition to the UNASSIGNED state), as it is assumed that the FE
state is unknown.
RX_link_blocked_timeout
In the case of link inhibiting, this value determines how long the RX LSM should stay in
the BLOCKED state before it can move to the UNUSABLE state (if the FE does not report
TX != Active). The set_rx_phy_defect command immediately terminates this timer
(causing an immediate transition to the UNUSABLE state), as it is assumed that the FE
state is unknown.
