G120, LDR0 and LDR1

Is there any description for the LDR0 and LDR1?

Does the G120 support more bootloader modes then the USBizi?

No description yet but yes it has more than USBizi as it uses TinyBooter like EMX. It shouldn’t be more than a week before we have more details.

I think, but do not go off this as final answer, that both LDR pins are pulled up internally where setting LDR1 low will put the device in GHI loader mode and setting both LDR pins low will set the device in TinyBooter. Setting LDR2 low alone has no effect.
