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.

Selects the length of time required before accessing a new row.

Selects length of time from read to pre-change.
