Modified 09-10-2009 for attiny45 A.Saporetti
|

Modified for Atmel ATTiny2313 mcu by Ren<65> 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.
