91Board description
92-----------------
93
94Clock rate:     40MHz (board can run up 66MHz with alternate OSC)
95Bus width:      32 bit Flash, 64 bit SDRAM
96FLASH:          8M SIMM
97RAM:            16M SDRAM DIMM
98
99The board is marked with "Rev PILOT"
100U17 is marked with "MPC8260ADS Pilot 00"
101The processor is marked with "XPC8260ZU166 166/133/66 MHz"
102
103
104Board Configuration:
105--------------------
106
107The evaluation board has a number of configurable options:
108
109DIP switch settings used:
110DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off"
111DS2: all "on"
112DS3: all "on"
113
114A 40MHz oscillator is fitted to U16.
115
116
117Board Connections:
118------------------
119
120Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to
121get console I/O. A 9way male-female straight-through cable is required to
122connect to a PC.
123
124If you require the network connections (see README in network directory)
125you need to connect 3VTTL - RS422 level convertors to the CPM expansion
126connector, P4. The signals, as numbered on the connector itself
127(beware: the numbering on the PCB does not agree):
128
129TX Data  (SCC3 TXD) (output) Pin a25
130TX Clock (BRG4O)    (output) Pin a11
131Rx Data  (SCC3 RXD) (input)  Pin c15
132Rx Clock (CLK5)     (input)  Pin d28
133Ground   (GND)      (n/a)    Pin c1
134
135
136Debugging/ Code loading:
137------------------------
138
139Tested using the Metrowerks debugger and Macraigor OCDemon (Raven). 
140The OCD connects via the parallel port and allows you to download code
141to the board.  It may be possible to use some other debugger if you
142don't already have Metrowerks CodeWarrior.
