9.3.2.2 Page Buffer Load
The page buffer is loaded by writing directly to the memories as defined in the memory map.
Flash, EEPROM, and User Row share the same page buffer, so only one section can be
programmed at a time. The Least Significant bits (LSb) of the address are used to select
where in the page buffer data are written. The resulting data will be a binary
AND operation between the new and the previous content of the page
buffer. The page buffer will automatically be erased (all bits set) after:
- A device Reset
- Any page write or erase operation
- A Clear Page Buffer command
- A device wake-up from any sleep mode
