Bits 21:0 – ADDR[21:0] NVM Address

ADDR drives the hardware half-word offset from the start address of the corresponding NVM section when a command is executed using CMDEX. The effective address for the operation is start address of the SECTION_ADDRESS + 2*ADDR. This register is also automatically updated when writing to the page buffer.

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
