reg_ddrc_addrmap_col
_b6
19:16 rw 0x0 Full bus width mode: Selects the address bits used
as column address bits 7.
Half bus width mode:
Selects the address bits used as column address
bits 8. Valid range is 0-7. Internal Base 9. The
selected address bit for each of the column
address bits is determined by adding the Internal
Base to the value of this field.
