IMPORTANT: Microcontroller with FLASH.The following describes the buffer setup:The addresses $E000 to $FDFF are FLASH .The address $FF7E is FLASH Block Protect Register.The addresses $FFDC to $FFFF are Flash 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 clock trim valuesstored at locations $FF80 and $FF81. If these values need to be saved on blank devicesfrom the factory disable Erase before Program.This algorithm does not program the clock trim registers.
