Reset Interrupt (RSTI)
This is the Reset interrupt bit.
RSTI Interrupt [4]
2.8.23 Start Block Address Register F24Ch (R/W)
This Read/Write register shows the NAND Flash block address in the Write Protection mode. Setting this register precedes a 'Lock Block'
command, 'Unlock Block' command, or ‘Lock-Tight' Command.
F24Ch, default = 0000h
2.8.24 Start Block Address Register F24Dh (R/W)
This register is reserved for future use.
2.8.25 NAND Flash Write Protection Status Register F24Eh (R)
This Read register shows the Write Protection Status of the NAND Flash memory array.
To read the write protection status, FBA(DFS and DBS also in case of DDP) has to be set before reading the register.
F24Eh, default = 0002h
