4.4.3 Block Refills
The BBCC can request a block refill if the fetch resides in cacheable
space. If the address is cacheable then a block fetch is started by the
BBCC starting with the desired word first. The IBLKSZ and DBLKSZ bits
in the SCR selects block sizes of two, four, or eight. Instruction block size
and data block size are controlled separately. When the end of the block
is reached, the BBCC wraps around and requests the first word of the
block until the entire block is refilled. The external memory system can
terminate the block request at any time.
