87Board description
88-----------------
89
90Clock rate:     40MHz (board can run up 66MHz with alternate OSC)
91Bus width:      32 bit Flash, 64 bit SDRAM
92FLASH:          8M SIMM
93RAM:            16M SDRAM DIMM
94
95The board is marked with "Rev PILOT"
96U17 is marked with "MPC8260ADS Pilot 00"
97The processor is marked with "XPC8260ZU166 166/133/66 MHz"
98
99
100Board Configuration:
101--------------------
102
103The evaluation board has a number of configurable options:
104
105DIP switch settings used:
106DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off"
107DS2: all "on"
108DS3: all "on"
109
110A 40MHz oscillator is fitted to U16.
111
112
113Board Connections:
114------------------
115
116Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to
117get console I/O. A 9way male-female straight-through cable is required to
118connect to a PC.
119
120If you require the network connections (see README in network directory)
121you need to connect 3VTTL - RS422 level convertors to the CPM expansion
122connector, P4. The signals, as numbered on the connector itself
123(beware: the numbering on the PCB does not agree):
124
125TX Data  (SCC3 TXD) (output) Pin a25
126TX Clock (BRG4O)    (output) Pin a11
127Rx Data  (SCC3 RXD) (input)  Pin c15
128Rx Clock (CLK5)     (input)  Pin d28
129Ground   (GND)      (n/a)    Pin c1
130
131
132Debugging/ Code loading:
133------------------------
134
135Tested using the Metrowerks debugger and Macraigor OCDemon (Raven). 
136The OCD connects via the parallel port and allows you to download code
137to the board.  It may be possible to use some other debugger if you
138don't already have Metrowerks CodeWarrior.
