[Icc-avr] Data sheet problems???

[John Baraclough]

Having worked for a major semi-conductor manufacturer for several years 
I can tell you that most data sheets are written by copy & paste from an 
earlier similar product. In the megaAVR series a wide variety of pins 
are used for TOSC1 & 2; mega8 uses PB6 & 7, mega32 uses PC6 & 7, mega128 
uses PG4 & 3 and m169 uses XTAL1 & 2.

It is highly probable that the pinout diagram for your particular chip 
is correct and the text is wrong. Report the error to Atmel, but don't 
expect a change in the data sheet in short order.

All the best for now,
John
