C3AB0: Audio Port Trap Mask Register
Configuration space; function 3; offset: B3-B0h. Default: 0707_010Fh. Read-write.
31:24
MASKAUD4
MASKAUD[4:1]. Address masks for the audio trap event. See C3AA8 for details.
C3AB4: PCMCIA Trap 1 and 2 IO Address Register
Configuration space; function 3; offset: B7-B4h. Default: 0000_0000h. Read-write.
C3AB4, C3AB8, C3ABC, and C3AC0 combine to specify the address for the PCMCIA1 and PCMCIA2 trap events.
These events may be used to generate an SMIs or SCIs or reload the system inactivity timer. The PCMCIA1 and
PCMCIA2 trap events occur when the following is true:
PCMCIA1:
| ( (AD[31:10]| MASKPME1 == ADDRPME1 | MASKPME1) & (PCI memory space access) );
PCMCIA2:
| ( (AD[31:10]| MASKPME2 == ADDRPME2 | MASKPME2) & (PCI memory space access) );
Where AD is the address phase of a PCI bus cycle. It is not necessary for the cycle to be targeted at the IC. The IO
space mask bits cover bits[7:0]. The memory space mask bits cover bits[17:10].
31:16
ADDRPIO2
ADDRPIO1 and ADDRPIO2. IO address for the PCMCIA1 and PCMCIA2 trap events.
C3AB8: PCMCIA Trap 1 Memory Address Registers
Configuration space; function 3; offset: BB-B8h. Default: 0000_0000h. Read-write.
31:10
ADDRPME1
ADDRPME1. Memory address for the PCMCIA1 trap event. See C3AB4 for details.
C3ABC: PCMCIA Trap 2 Memory Address Registers
Configuration space; function 3; offset: BF-BCh. Default: 0000_0000h. Read-write.
31:10
ADDRPME2
ADDRPME2. Memory address for the PCMCIA2 trap event. See C3AB4 for details.
C3AC0: PCMCIA Trap Mask Registers
Configuration space; function 3; offset: C3-C0h. Default: 0000_0000h. Read-write.
31:24
MASKPME2
