56 Freescale Semiconductor

Preliminary

4.8 Factory Programmed Memory

The Boot Flash memory block is programmed during manufacturing with a default Serial Bootloader

program. The Serial Bootloader application can be used to load a user application into the Program and

Data Flash (NOT available in the 56F8123) memories of the device. The 56F83xx SCI/CAN Bootloader

User Manual provides detailed information on this firmware. An application note, Production Flash

Programming, details how the Serial Bootloader program can be used to perform production Flash

programming of the on-board Flash memories as well as other optional methods.

Like all the Flash memory blocks, the Boot Flash can be erased and programmed by the user. The Serial

Bootloader application is programmed as an aid to the end user, but is not required to be used or maintained

in the Boot Flash memory.
