Macro reference

Read

	Read
Reads a single value from the Flash EEPROM at the specified address
- UINT	Address

- ULONG	Return

Write

	Write
Writes a single value to the Flash EEPROM at the specified address
- UINT	Address

- ULONG	Data

- VOID	Return

Property reference

	Properties
	Enabled
Is the Flash EEPROM component currently supported on the selected MCU device?
	Number Of Values
Number of individual values that can be read and written using the component. The more values you want the bigger the RAM buffer required to store the data when performing a write.
	Flash Page
Flash Page to use as EEPROM
	Flash Address

	Initialiser

	Bits Per Value
Number of bits available when initialising the Flash memory.
	Bits Per Instruction
Number of bits that can be stored or retreived using a single flash address
