IP100-DS-R03
May 27, 2003
BIT DESCRIPTION
Header Type. If the Reserved/MultiFunction bit in the AsicCtrl
register is a logic 0, HeaderType is set to 0x00 identifying the IP100
as a single-function PCI device and specifying the configuration
register layout.
If the Reserved/MultiFunction bit in the AsicCtrl register is a logic 1,
HeaderType is set to 0x80 identifying the IP100 as a multi-function
PCI device and specifying the configuration register layout.
10.6.12 InterruptLine
Class............................. LAN PCI Configuration Registers, Configuration
Base Address ............... PCI device configuration header start
Address Offset .............. 0x3c
Default .......................... 0x00
Width ............................ 8 bits
BIT
BIT NAME
R/W
7..0
InterruptLine
R/W
BIT DESCRIPTION
Interrupt Line. InterruptLine specifies the interrupt level used by the
IP100. By setting InterruptLine the host system may configure the
appropriate interrupt vector for its Interrupt Service Routine.
For 80x86 processor based host systems, InterruptLine corresponds
to the IRQ number (0x00 through 0x0F), with the value 0xFF
corresponding to disabled interrupts.
10.6.13 InterruptPin
Class............................. LAN PCI Configuration Registers, Configuration
Base Address ............... PCI device configuration header start
Address Offset .............. 0x3d
Default .......................... 0x01
Width ............................ 8 bits
BIT
BIT NAME
R/W
7..0
InterruptPin
R
BIT DESCRIPTION
Interrupt Pin. InterruptPin indicates which PCI interrupt signal the
IP100 will utilize. The IP100 always utilizes the INTAN interrupt
signal, corresponding to an InterruptPin value of 0x01.
