rx_hval_tlp
The 8 MSBs of this signal also report the type and format of the
transaction when
Receive sequencing valid. This is a sequencing signal pulse. All
previously-described signals (
only when this signal is asserted.
Transmit request to data link layer. This signal is a global virtual
channel request for transmitting transaction layer packet to the
data link layer.
Transmit request acknowledge from data link layer. This signal
serves as the acknowledge signal for the global request from
the transaction layer when accepting a transaction layer packet
from the data link layer.
Transmit data requested from data link layer. This is a
sequencing signal that makes a request for next data from the
transaction layer.
Transmit nullify transaction layer packet request. This signal is
asserted by the transaction layer in order to nullify a transmitted
transaction layer packet.
Transmit virtual channel arbitration result. This signal reports
arbitration results of the transaction layer packet that is currently
being transmitted.
Transmit sequencing valid. This signal, which depends on the
number of initialized lanes on the link, is a sequencing signal
pulse that enables data transfer from the transaction layer to the
data link layer.
Power management state machine. This signal indicates the
power management state machine encoding responsible for
scheduling the transition to legacy low power:
