For endpoints, only INTA messages are
generated.
For root port, legacy interrupts are translated
into TLPs of type Message Interrupt which
triggers the int_status[3:0] signals to the
application layer.:

The pme_to_cr signal sends and acknowledges
this message:
■
■
int_status[0]: Interrupt signal A
int_status[1]: Interrupt signal B
int_status[2]: Interrupt signal C
int_status[3]: Interrupt signal D
Root Port: When pme_to_cr is asserted, the
Root Port sends the PME_turn_off message.
Endpoint: When pme_to_cr is asserted to
acknowledge the PME_turn_off message by
sending pme_to_ack to the root port.
