Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.

| 7:0 | value | The die_mask register information will be used for devices having address restrictions. For example, in certain Samsung devices, when the first address in a two-plane command is being sent, it is expected that the address is all zeros. But if the NAND device internally has multiple dies stacked, the die information (MSB of final row address) has to be sent. The value programmed in this register will be used to mask the address while sending out the last row address. |
