13.2.7 CACHE LINE REGISTER – OFFSET 0Ch
Bit
Function
Type
Description
7:0
Cache Line
Size
RW
Designates the cache line size for the system and is used when terminating
memory write and invalidate transactions and when prefetching memory read
transactions.
Only cache line sizes (in units of 4-byte) which are a power of two are valid (only
one bit can be set in this register; only 00h, 01h, 02h, 04h, 08h, and 10h are valid
values).
Reset to 0
13.2.8 PRIMARY LATENCY TIMER REGISTER – OFFSET 0Ch
Bit
Function
Type
Description
15:8
Primary
Latency timer
RW
This register sets the value for the Master Latency Timer, which starts counting
when the master asserts FRAME#.
Reset to 0
