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 56F8146 device) memories of the device. The 56F83xx SCI/CAN
Bootloader User Manual (MC56F83xxBLUM) provides detailed information on this firmware. An
application note, Production Flash Programming (AN1973), details how the Serial Bootloader program
can be used to perform production Flash programming of the on-board Flash memories as well as other
potential 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.
Part 5 Interrupt Controller (ITCN)
5.1 Introduction
The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to
signal to the 56800E core when an interrupt of sufficient priority exists, and to what address to jump in
order to service this interrupt.
5.2 Features
The ITCN module design includes these distinctive features:
