26.6.8 Address

Only the number of bits required to access the memory is used.

Note: Access to the Flash is double-word granular (32 bits), while the address space for the Flash array is byte granular. This means that not all bits of ADDR are needed to access a double word in Flash. As a result, ADDR[1:0] is ignored and will always read as 0.

Bits 31:0 – ADDR[31:0] NVM Address

ADDR drives the address to the NVM when a command is executed using CMDEX.

This register is also automatically updated when writing to an address in the Flash.
