cache15 (d_slide_data) - Primary Data RAM Data Line Test
This tests the data lines to the primary data cache. A sliding one and a sliding zero data
pattern is written into the first location of the D-cache to check if each data line can be
toggled individually.
Possible errors:
0107023: D-cache data ram data lines failed walking one test
Addr: 0x%08x Expected: 0x%08x Actual: 0x%08x Xor: 0x%08x

Addr: 0x%08x Expected: 0x%08x Actual: 0x%08x Xor: 0x%08x
cache16 (d_slide_addr) - Primary Data RAM Address Line Test
This tests the address lines to the primary data cache. Each address line to the data cache is
toggled once individually by sliding a one and then a zero across the address lines.
Possible errors:
0107025: D-cache data ram address lines failed walking one test
Addr: 0x%08x Expected: 0x%08x Actual: 0x%08x Xor: 0x%08x
