Way Enable Register (WayEnable)

(Ask a Question)

The WayEnable register determines which ways of the L2 cache controller are enabled as cache. Cache ways which are not enabled, are mapped into the L2-LIM as described in MSS Memory Map.

This register is initialized to 0 on reset and may only be increased. This means that, out of Reset, only a single L2 cache way is enabled as one cache way must always remain enabled. Once a cache way is enabled, the only way to map it back into the L2-LIM address space is by a Reset.
