INTA Assertion Disable (INTAAD): 
0 = This device is permitted to generate INTA interrupt messages.
1 = This device is prevented from generating interrupt messages. Any INTA 
emulation interrupts already asserted must be de-asserted when this bit is 
set. 
Only affects interrupts generated by the device (PCI INTA from a PME event) 
controlled by this command register. It does not affect upstream MSIs, upstream 
PCI INTA-INTD assert and de-assert messages.
