MAX_LAT
RU
Maximum latency. The contents of this field may be used by host BIOS to assign an arbitration priority level
to the Smart Card controller. The default for this register indicates that the Smart Card controller may need
to access the PCI bus as often as every 0.25 µs; thus, an extremely high priority level is requested. The
contents of this field may also be loaded through the serial EEPROM.
9.17 Capability ID and Next Item Pointer Registers
The capability ID and next item pointer register identifies the linked-list capability item and provides a pointer to the
next capability item. See Table 9−10 for a complete description of the register contents.

NEXT_ITEM
R
Next item pointer. The Smart Card controller supports only one additional capability, PCI power
management, that is communicated to the system through the extended capabilities list; therefore,
this field returns 00h when read.
7−0
CAPABILITY_ID
R
Capability identification. This field returns 01h when read, which is the unique ID assigned by the PCI
SIG for PCI power-management capability.
