Library Functions
EEPROM_READ, EEPROM_WRITE
Synopsis
Description
These functions allow access to the on-chip eeprom (when present). The eeprom is not in the
directly-accessible memory space and a special byte sequence is loaded to the eeprom control regis-
ters to access this memory. Writing a value to the eeprom is a slow process and the eeprom_write()
function polls the appropriate registers to ensure that any previous writes have completed before
writing the next datum.
completion.
Example

flash_erase, flash_read, flash_write
Reading data is completed in the one cycle and no polling is necessary to check for a read
