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.
