The I C interface has additional overhead when reading Flash memory pages. Reviewing Figure 22 shows how the
data is presented during a multiple page read request. When the page count is three, and the Page Address
2
Pointer is 0000, the I C interface will return Page 0, 16 undefined bytes, Page 0, 4 dummy bytes, and Page 1.
Reading the final four dummy bytes is optional.
