Start Address2 Information

In the case of writing Register, both registers in chip1 and chip2 will be written regardless of DBS. Reading out from Register of chip1/chip2
follows the DBS setting.
In using DDP chip, BootRAM of Chip 1 will always be selected regardless of DBS.
Reading and Writing on the DataRAM of DDP chip is different. Only the DataRAM selected by DBS will be written and read out.
