28.6.3.3.1 Function eeprom_emulator_write_buffer()

Writes a buffer of data to the emulated EEPROM memory space.

enum status_code eeprom_emulator_write_buffer( const uint16_t offset, const uint8_t *const data, const uint16_t length)

Writes a buffer of data to a section of emulated EEPROM memory space. The source buffer may be of any size, and the destination may lie outside of an emulated EEPROM page boundary.

Note: Data stored in pages may be cached in volatile RAM memory; to commit any cached data to physical non-volatile memory, the eeprom_emulator_commit_page_buffer() function should be called.
