Board description
-----------------

Clock rate:     40MHz (board can run up 66MHz with alternate OSC)
Bus width:      32 bit Flash, 64 bit SDRAM
FLASH:          8M SIMM
RAM:            16M SDRAM DIMM

The board is marked with "Rev PILOT"
U17 is marked with "MPC8260ADS Pilot 00"
The processor is marked with "XPC8260ZU166 166/133/66 MHz"


Board Configuration:
--------------------

The evaluation board has a number of configurable options:

DIP switch settings used:
DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off"
DS2: all "on"
DS3: all "on"

A 40MHz oscillator is fitted to U16.


Board Connections:
------------------

Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to
get console I/O. A 9way male-female straight-through cable is required to 
connect to a PC.

If you require the network connections (see README in network directory)
you need to connect 3VTTL - RS422 level convertors to the CPM expansion 
connector, P4. The signals, as numbered on the connector itself
(beware: the numbering on the PCB does not agree):

TX Data  (SCC3 TXD) (output) Pin a25
TX Clock (BRG4O)    (output) Pin a11
Rx Data  (SCC3 RXD) (input)  Pin c15
Rx Clock (CLK5)     (input)  Pin d28
Ground   (GND)      (n/a)    Pin c1


Debugging/ Code loading:
------------------------

Tested using the Metrowerks debugger and Macraigor OCDemon (Raven).  
The OCD connects via the parallel port and allows you to download code 
to the board.  It may be possible to use some other debugger if you
don't already have Metrowerks CodeWarrior.
