ADDR drives the hardware half-word offset from the start
address of the corresponding NVM section when a command is executed using CMDEX. This
register is also automatically updated when writing to the page buffer. The effective
address for the operation is Start address of the section + 2*ADDR.
Example:
For erasing the 3rd row in the Flash memory, spanning from 0x00000200 to 0x000002FF,
ADDR must be written with the half-word offset address of any half-word within this
range, that is any value between 0x100 and 0x17F.
For erasing the 5th row in the RWWEE memory, spanning from 0x00400400 to 0x004004FF,
ADDR should be written with the half-word offset address of any half-word within this
range, that is any value between 0x200 and 0x27F.
