Strip addresses are 12-bit fields densely packed into 32-bit words. This means that some strip addresses cross 32 bit boundaries. Since every 3 32-bit words will contain exactly 8 strip addresses, the pattern repeats every 3 32-bit words.
This structure maps out how the part of second strip address, the third and fourth strip addresses and part of the fifth address fits in the second word of this three word pattern.
See also _TKR_8strips0_bf and _TKR_8strips2_bf, which gives the mapping for the other 2 words.
