2.8.9 Start Address1 Register F100h (R/W)
This Read/Write register describes the NAND Flash block address which will be loaded, programmed, or erased.
F100h, default = 0000h
NOTE :
For QDP, See Section 7.4
Start Address1 Information
2.8.10 Start Address2 Register F101h (R/W)
This Read/Write register describes the method to select the BufferRAM of DDP (Device BufferRAM Select)
F101h, default = 0000h
Start Address2 Information
>DBS should be set to 1 when accessing the BufferRAM of the second chip(MSB chip) in a DDP.
>Since DDP chip has 2 BufferRAMs multiplexed, the BufferRAM which corresponds to the Flash core that is intended to be
accessed must be selected using DBS.
>Data in BufferRAM of one chip is not accessible to the Flash Core of the other chip in a DDP See Section 7.4.
2.8.11~15 Start Address3~7 Register F102h~F106h
This Register is reserved for future use.
