Burst Buffer Controller 2 Module
4.5.1.1
Write access to any BBC special purpose register invalidates all BTB entries.
4.5.1.2
The BTB operation may be enabled or disabled by programming the BTEE bit in the BBCMCR register.
4.5.1.3
The BTB operation may be inhibited regarding some memory regions. The BTB caching is inhibited for
a region if the BTBINH bit is set in the region attribute register (or global region attribute register). See
