Description
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."
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.
Sets extended memory configuration options to Auto or
User Defined.
Selects the number of clock cycles required to address
a column in memory.
Selects the number of clock cycles between addressing
a row and addressing a column.
