CB[2:0] - Column address bits: #bits = 6 +CB[2:0]
RB[2:0] - Row address bits: #bits = 10 +RB[2:0]
BB[1:0] - Bank address bits: #bits = 2 +BB[1:0]
These three fields indicate how many column, row, and bank
address bits are present. An offset of {6,10,2} is added to the
field value to give the number of address bits.
