Cap_Ptr (Offset 0x34)
The Capabilities Pointer field (Cap_Ptr) is an 8-bit field that provides an offset in the
device's PCI configuration space for the location of the first item in the capabilities
linked list. The 82574L sets this bit, and implements a capabilities list, to indicate that
it supports:
Its value, 0xC8, is the address of the first entry: PCI power management.
Interrupt Line (Offset 0x3C)
Read/write register programmed by software to indicate which of the system interrupt
request lines this device's interrupt pin is bound to. See the PCI definition for more
details.
Interrupt Pin (Offset 0x3D)
Read-only register. The LAN implements legacy interrupt on INTA.
Max_Lat/Min_Gnt (Offset 0x3E)
Not used. Hardwired to 0b.
PCI Power Management Registers
All fields are reset on full power up. All of the fields except PME_En and PME_Status are
reset on exit from D3cold state.
See the detailed description for registers loaded from the NVM at initialization time.
Initialization values of the configuration registers are marked in parenthesis.
Some fields in this section depend on the Power Management Ena bits in the NVM word
0x0A.
