• Manufacturer Part Number: AN2183
• Description: Using FLASH as EEPROM on the MC68HC908GP32
• Manufacturer: Freescale Semiconductor / Motorola

Application Note
Write FlashEE (W)
Dump FlashEE (D)
Summary
12
After entering the single character W, followed by either "1" or "2", the
program will respond by prompting the user to enter a data block string
of data. Each entry must be a valid hexadecimal value and is echoed
back as typed. Entering a non-hexadecimal value results in the process
being stopped with the default prompt being output. After entering the
required number of bytes, the FlashEE is programmed with the data
provided.
This command will output the current contents of the selected FlashEE
section.
Most projects using the M68HC908 Family of microcontrollers requiring
nonvolatile data storage that is application software programmable need
not incur the added cost of external EEPROM devices. A method for
using the on-chip FLASH memory for such application purposes has
been demonstrated with this application note.
