 		 #93892 - More I/O
Responding to: ???'s previous message
Jan Waclawek said:
It would be possible to configure both (and also ALE; and eventually RESET/XTALs if internal POR/BOD/WD and RC oscillator is present and used) by fuses at programming time, though.

That would leave only the power pins unusable for I/O :-D


The Philips 89LPC9xx family have on-chip RC oscillators and on-chip flash, along with the option to use /RST as an I/O pin, leaving only the power pins unusable for I/O.
