11.2
Figure 11-2 shows how to cascade up to four blocks. Each block contains up to eight CYNSE70128 devices except the last, and
the interconnection within each was shown in the previous subsection with the cascading of up to eight devices in a block.
The interconnection between blocks for depth-cascading is important. For each Search, a block asserts BHO[2], BHO[1], and
BHO[0]. The BHO[2:0] signals for a block are the signals taken only from the last device in the block. For all other devices within
that block, these signals stay open and floating. The host ASIC must program the table size (TLSZ) field to 10 in each of the
devices for cascading up to 31 devices (in up to four blocks).
