I was wondering if it was possible to use port pin PA1 (on the XTAL2 line) on a tiny2313 while it is being driven on XTAL1 by an external clock.
The datasheet for the Mega168 says you can do that.
(pg. 77: "XTAL2: Chip clock Oscillator pin 2. ... When external clock is connected to XTAL1 this pin can be used as an I/O pin.")
The datasheet for the tiny2313 doesn't mention it.
(pgs. 26, 52)
Anyone tried this on a tiny2313?
Did it work?
edited to fix Mega number. I meant 168, not 163
