Modified for Atmel ATTiny2313 mcu by René Bohne
|
|
|
|
Corrected 17-05-2010 for ATtiny84 B.Cook ...
|
|
|
|
The default analog_reference leaves chip pin 13 (digital pin 10; PA0)
|
|
unconnected. So the pin can be set to a non-floating state and so the
|
|
pin can be used as another digital pin, support for digital pin 10 was
|
|
added.
