PAGEN: Page number
The PAGEN field is used to address a page or fuse bit for certain operations. In order to sim-
plify programming, the PAGEN field is automatically updated every time the page buffer is
written to. For every page buffer write, the PAGEN field is updated with the page number of
the address being written to. Hardware automatically masks writes to the PAGEN field so that
only bits representing valid page numbers can be written, all other bits in PAGEN are always
0. As an example, in a flash with 1024 pages (page 0 - page 1023), bits 15:10 will always be 0.
Table 18-6.
KEY: Write protection key
This field should be written with the value 0xA5 to enable the command defined by the bits of
the register. If the field is written with a different value, the write is not performed and no action
is started.
This field always reads as 0.
