MB_START_ADDR: Memory Test Start Address
MB_END_ADDR row and column address must be larger than MB_START_ADDR row
and column address in either increasing or deceasing address mode.
During FastX, FastY and FastXY operation, only one memory bank is tested. Specify the
desired bank in MB_START_ADDR[2:0]. MB_END_ADDR[2:0] is ignored.
This register is only used when MBCSR.atype = 2b’10, and when MBCSR.algo is
non-zero.
