EEPROM Emulation for MC9S12C32

EEstudent — Wed, 23 Apr 2008 03:35:02 GMT

Does anyone have any example code for emulating EEPROM on a MC9S12C32? This has been stumping my microcontroller applications teacher and myself. Any help what-so-ever would be greatly appreciated. If I show your code to my instructor, you will be cited. He encourages us to scour the web for help if we get stuck. I am definately stuck. Thanks...

You need AN2204 "Fast NVM Programming for the MC9S12DP256" and the SW file for it.

This is sample code to program flash.

Here is a link, look down the page.

I would also suggest taking a look at AN2720, this AN is a bit more recent than the one Jim referenced.

Hello

The AN2302 is written specifically for EE emulation on the MC9S12C32 http://www.freescale.com/files/microcontrollers/doc/app_note/AN2302.pdf?fsrch=1&WT_TYPE=Application%20Notes&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation

This also includes code examples.
