Read from or write to EEPROM/data a byte, word or double word. Available procedures: * data_eeprom_read(, ) * data_eeprom_write( , ) * data_eeprom_read_word( , ) * data_eeprom_write_word( , ) * data_eeprom_read_dword( , ) * data_eeprom_write_dword( , ) Available functions: * = data_eeprom( ) * = data_eeprom_word( ) * = data_eeprom_dword( ) In all cases is a word containing the position relative to the beginning of EEPROM/data memory. Examples of use: * Read a byte of EEPROM at offset 7 into x: var byte x data_eeprom_read(7, x) * Read a word from EEPROM at offset 4 into y: var word y y = data_eeprom_word(4) * Write a byte to EEPROM at offset 18: data_eeprom_write(18, 0b1111_0000)
* Write-protect bits in configuration memory may prohibit writing. * Writing to locations outside the available memory range may have unexpected effects! * For most PICs the first EEPROM address starts at 0. For some PICs, this is not the case and and an offset must be added to the EEPROM address If an offset is needed the main program can define a constant called EEPROM_ADDRESS_OFFSET with the correct value so that the first address of the EEPROM remains 0 for the user. Some examples: For PIC16F18346: const word EEPROM_ADDRESS_OFFSET = 0x7000 For PIC18F46Q10: const dword EEPROM_ADDRESS_OFFSET = 0x31_0000 See the datasheet of the PICs for more information.
