KSZ8841-PMQL
October 2007
33
M9999-100407-1.5
Bit
Default
Description
Provides interrupt line routing information. The basic input/output system
(BIOS) writes the routing information into to this field when it initialized and
configures the system. The value in this field indicates which input of the
system interrupt controller is connected to the K8841P’s interrupt pin. The
driver can use this information to determine priority and vector information.
Values in this field are system architecture specific.
The following table shows the access rules of the register.

Value after hardware reset
0x281401XX
Capabilities ID Register (CCID Offset 50H)
The CCID register is a read-only register that provides information on the KSZ8841-PMQL power management
capabilities. The following table shows the CCID register bit fields. The CCID register bits [31-16] are mirrored with
PMCR register bits [15-0].
Bit
Default
Description
31
0
PME Support D3 (cold)
If this bit is set, the KSZ8841-PMQL asserts PME in D3(cold) power state.
Otherwise,
the KSZ8841-PMQL does not assert PME in D3(cold).
The value of this bit is loaded from the PME_D3_cold bit in the EEPROM.
30
1
PME Support D3 (hot)
The value of this bit is 1, indicating that the KSZ8841-PMQL may assert
PME in
D3(hot) power state.
29
0
PME Support D2
If this bit is set, the KSZ8841-PMQL asserts PME in D2 power state.
Otherwise, the
KSZ8841-PMQL does not assert PME in D2 state.
The value of this bit is loaded from the PME_D2 bit in the EEPROM.
28
0
PME Support D1
If this bit is set, the KSZ8841-PMQL asserts PME in D1 power state.
Otherwise, the
KSZ8841-PMQL does not assert PME in D1 state.
The value of this bit loaded from the PME_D1 bit in the EEPROM.
27
0
PME Support D0
1
The value of this bit is 0, indicating that the KSZ8841-PMQL does not
assert PME in
D0 power state.
26
0
D2 Support
If this bit is set, it indicates that the KSZ8841-PMQL support D2 power
state.
The value of this bit is loaded from the D2_SUP bit in the EEPROM.
1 References to D0, D1, D2, and D3 are power management states defined in a similar fashion to the way they are defined for PCI.
