USB PCI Host Controller
8.2.1.8
Latency Timer register
This register specifies—in units of PCI bus clocks—the value of the Latency Timer for the
PCI bus master.
Table 14
shows the bit description of the Latency Timer register.
8.2.1.9
Header Type register
The Header Type register identifies the layout of the second part of the predefined header,
beginning at byte 10h in configuration space. It also identifies whether the device contains
multiple functions. For bit allocation, see
Table 15
.
8.2.1.10
Base Address register 0
Power-up software must build a consistent address map before booting the machine to an
operating system. This means it must determine how much memory is in the system, and
how much address space the I/O controllers in the system require. After determining this
information, power-up software can map the I/O controllers into reasonable locations and
proceed with system boot. To do this mapping in a device-independent manner, the base
registers for this mapping are placed in the predefined header portion of configuration
space.
Bit 0 in all Base Address registers is read-only and used to determine whether the register
maps into memory or I/O space. Base Address registers that map to memory space must
return logic 0 in bit 0. Base Address registers that map to I/O space must return logic 1 in
bit 0.
The bit description of the BAR 0 register is given in
Table 17
.
