2.8.11  Start Address3 Register F102h (R/W)

This Read/Write register describes the NAND Flash destination block address which will be copy back programmed. Also, this register indi-
cates the block address for the first page to be read in Cache Read Operation.

F102h, default = 0000h

Start Address3 Information

2.8.12 Start Address4 Register F103h (R/W)  

This Read/Write register describes the NAND Flash destination page address in a block and the NAND Flash destination sector address in a
page for copy back programming. Also, this register describes the first page and sector address to be loaded in Cache Read Operation.

F103h, default = 0000h

NOTE :

1) In case of  ‘Cache Read Operation’, FCSA has to be set to 00.
