Hi, I am starting a new project using the MC9S08AC16.  I need to use the FLASH to store data that is occasionally updated.  I upgraded from using an MC68HC908JL8 which had Freescale ROM resident routines for handling flash since you could not program FLASH and execute from it at the same time.  This new chip does not seem to have the same limitation on the FLASH.  Is this True?  I cannot find anywhere in the reference manuals any mention of ROM resident routines or the inability to Program FLASH while executing from FLASH.  Can anyone verify this?  Thanks!
