6.3.2 Register Summary
The tables in this subsection summarize the registers of
the Core Logic module. Included in the tables are the regis-
ter’s reset values and page references where the bit for-
mats are found.
Note: Function 4 (F4) is for Video Processor support
(although accessed through the Core Logic PCI
configuration registers). Refer to Section 7.3 "Reg-
ister Descriptions" on page 333 for details.
