The submenu represented by Table 11 is for setting video memory cache mode.  This submenu 
becomes available when User Defined is selected under Extended Configuration. 

Feature Options 

Extended Configuration 

•  Default (default) 
•  User-Defined 

User Defined allows setting memory control and video 
memory cache mode.  If selected here, will also display 
in the Advanced Menu as: “Extended Menu: Used.” 

Video Memory Cache Mode 

•  USWC 

 
 
 
 
 

•  UC (default) 

Selects Uncacheable Speculative Write-Combining 
(USWC) video memory cache mode.  Full 32 byte 
contents of the Write Combining buffer are written to 
memory as required.  Cache lookups are not 
performed.  Both the video driver and the application 
must support Write Combining. 

Selects UnCacheable (UC) video memory cache mode.  
This setting identifies the video memory range as 
uncacheable by the processor.  Memory writes are 
performed in program order.  Cache lookups are not 
performed.  Well suited for applications not supporting 
Write Combining.
