BestComm XLB Address Snooping
13.14 BestComm XLB Address Snooping
BestComm prefetches data from the XLB into 4 32-Byte wide Read Line Buffers. A buffer will be invalidated, if the BestComm XLB Address
Snooping (BSDIS) is enabled, see XLB Arbiter Configuration Register, and a write operation on the XLB to the prefetched data address
happens. No invalidation of the buffer will happen if the BSDIS bit is set. BestComm will still use the old prefetched data.
