The M52277EVB contains two FlexBus memory sections. These two nonconsecutive sections were
arranged so that you can easily configure one to support glueless external memories like Flash or SRAM
and configure the other to use as space for unique chip-selects for non-cacheable, non-memory devices
like GPIO, control structures or other I/Os.

This section describes the major sections of the M52277EVB.
5.1
The MCF52277 processor is the fundamental control chip on the M52277EVB. This is a Version 2
ColdFire processor running at a maximum core speed of 160MHz. The M52277EVB allows you to fully
evaluate the feature set of the MCF52277 silicon. Refer to section 3.1 to review the list of board features.
5.2
Reset can be asserted through a push button switch, SW1. The push button switch is connected to the reset
line on the chip through a Dallas DS1834 Reset chip. Reset of the chip can also be caused by the on-board
BDM circuit, the University Breakout Connector, or the on board voltage regulator.
5.3
Two on-board clock sources are provided on the M52277EVB -- a 16MHz oscillator and a 16MHz crystal.
Alternatively, an input clock signal can be provided via an SMA connector for test purposes. The different
