These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to 
zero when this register is written. These bits will always return zero when read.

Bits 21:0 – ADDR[21:0]: NVM Address
ADDR drives the hardware (16-bit) address to the NVM when a command is executed using CMDEX. 8-bit 
addresses must be shifted one bit to the right before writing to this register.
This register is automatically updated when writing to the page buffer, and can also be manually written. This reg-
ister holds the address offset for the section addressed.
