The Partial Programming mode works only with 32-bit (or higher) boundaries. It cannot be used
with boundaries lower than 32 bits (8 or 16-bit for example).
After programming, the page (the whole lock region) can be locked to prevent miscellaneous
write or erase sequences. The lock bit can be automatically set after page programming using
WPL.
Data to be written are stored in an internal latch buffer. The size of the latch buffer corresponds
to the page size. The latch buffer wraps around within the internal memory area address space
and appears to be repeated by the number of pages in it.
Note:
Data are written to the latch buffer before the programming command is written to the Flash
Command Register MC_FCR. The sequence is as follows:
Two errors can be detected in the MC_FSR register after a programming sequence:
The entire memory can be erased if the Erase All Command (EA) in the Flash Command Regis-
ter MC_FCR is written.
• Write the full page, at any page address, within the internal memory area address space
• Programming starts as soon as the page number and the programming command are written

Writing of 8-bit and 16-bit data is not allowed and may lead to unpredictable data corruption.
