INTLINE
RW
Interrupt Line. The Interrupt Line register is an eight bit register used to com-
municate interrupt line routing information. The value in this register tells
which input of the system interrupt controller(s) the SSA7785 ThunderBird
Avenger Device's interrupt pin is connected to. If serial interrupts are
enabled (COMARCH0 Register IRQSER=1) then the INT_LINE register will
be read only and will have the value of all 1's. If Serial Interrupts are disabled
(IRQSER=0) then the INT_LINE register will be readable/writable.

INTPIN
RO
Interrupt Pin. The interrupt pin register tells which interrupt the SSA7785
ThunderBird Avenger device uses. If serial interrupts are enabled
(COMARCH0 Register IRQSER=1) then the INT_PIN register will have the
read only value of all 0's implying that the SSA7785 ThunderBird Avenger
device does not use any of the PCI Interrupt pins. If Serial Interrupts are dis-
abled (IRQSER=0) then the INT_PIN register will have the read only value of
01h implying that the SSA7785 ThunderBird Avenger device uses INT A
interrupt pin.
