This parameter determines when
the trigger output signal of the
LTSSM block should be asserted.
Additionally this information can be
translated into a trigger pulse on
entering or leaving the specified
state. This is done by the pulse
shaper of the Ctrl Out A connector
and no direct functionality of the
LTSSM.

Declaration (SCD) is a step for a
SuperSpeedPlus port, while in the
Polling.LFPS substate, to identify
itself as SuperSpeedPlus capable
by transmitting Polling.LFPS
signals with specific patterns
unique to SuperSpeedPlus ports.

1.9 µs – 2.5 us 2.2 µs LBPM is defined as a low power
signaling mechanism for two
SuperSpeedPlus ports to
communicate with each other
based on LFPS signals. The
adoption of Pulse Width
Modulation (PWM) is to embed the
transmitting clock in data and to
allow for easy data recovery at the
receiver based on LFPS clock.
