IMPORTANT: Microcontroller with FLASH.The following describes the Buffer setup:The addresses $C000 to $FDFF are Flash.The addresses $FF7E is Flash Block Protection Register(FLBPR).The addresses $FFDC to $FFFF are User Vectors.This device has an eight bytes security feature from $FFF6 to $FFFD. To read aprogrammed device with the security feature the Buffer or Device Configure mustbe filled with correct data from address $FFF6 to $FFFD. Incorrect data at theselocations will prevent access to the device.Erasing the device will erase the Trim and Calibration values stored atlocations $FD80:$FDDF and Reset Vector at $FFFE:$FFFF.If these values need to be saved on blank devices from the factoryplease use the other MM908E624ACDWB(Factory Trim) algorithm.This algorithm treats the Trim and Calibration and Reset Vector locationsas normal erasable/programmable flash memory.
