Read from or write to HEF/data a byte, word or double word. Available procedures: * data_hef_read(, ) * data_hef_write( , ) * data_hef_read_word( , ) * data_hef_write_word( , ) * data_hef_read_dword( , ) * data_hef_write_dword( , ) Available functions: * = data_hef( ) * = data_hef_word( ) * = data_hef_dword( ) In all cases must be in the range of the High Endurance Flash Examples of use: * Read a byte of HEF at offset 7 into x: var byte x data_hef_read(7, x) * Read a word from HEF at offset 4 into y: var word y y = data_hef_word(4) * Write a byte to HEF at offset 18: data_hef_write(18, 0b1111_0000)
AN1673. Using the PIC16F1XXX High-Endurance Flash (HEF) Block.
* You must always define the HEF offset address (start address of the HEF) by definining a connstant called HEF_ADDRESS_OFFSET with the correct value. See the datasheet of the PICs for more information. * Write-protect bits in configuration memory may prohibit writing. * Writing to locations outside the available memory range may have unexpected effects!

_hef_unlock()
Execute the High Endurance Flash unlock sequence for writing or erasing.
_hef_write_byte(word in address, byte in hef_data)
Write one byte to the High Endurance Flash. Data is written to Flash in rows of (14-bit) words, called a latch. We only store bytes here.
_hef_write_flash(word in address, byte in data, bit in latch)
Write a byte from the High Endurance Flash and return it.
_hef_erase(word in address)
Write a byte from the High Endurance Flash and return it.
data_hef(word in offset) return byte
Title: Read byte of data HEF at given offset Arguments: Offset in data HEF of byte to be read Returns: Byte of data HEF
data_hef_word(word in offset) return word
Title: Read word from data HEF at given offset Arguments: Offset in data HEF of word to be read Returns: Word of data HEF
data_hef_dword(word in offset) return dword
Title: Read doubleword from data HEF at given offset Arguments: Offset in data HEF of doubleword to be read Returns: Doubleword of data HEF
_hef_read_byte(word in address) return byte
Read a byte from the High Endurance Flash and return it. Note that although you can store (14-bit) words we only return one byte.
