Figure 26-3. Flash Addressing for Self-Programming

The Flash is word-accessed and organized in pages, so the Address Pointer can be considered as having two sections, as shown in the previous figure. The word address within the page (FWORD) is held by the Least Significant bits (LSbs) of the Address Pointer, while the Most Significant bits (MSbs) hold the Flash page address (FPAGE). Together, FWORD and FPAGE provide an absolute address to a word in the Flash.

The size of FWORD and FPAGE depend on the page and Flash size of the device.
