The MMA955xL platform has 16 KB of internal flash memory. There are ROM functions that allow erase and programming of that
memory. Chip supply voltage of 1.8V is sufficient for the flash programming voltage.
The size of the available flash memory varies between the different devices in the MMA955xL product family, as shown in the
following figure.
The smallest block of memory that can be written is 4 bytes and those 4 bytes must be aligned on a 4-byte boundary. The largest
block of memory that can be programmed is 128 bytes and the block must start at a 128-byte boundary.
Flash programming blocks must start on a 4-byte boundary and cannot cross a 128-byte page boundary.
