The I2C routines do not disable interrupts when the hardware I2C controller is used (e.g. channel 0).
ATtiny and ATmega target devices (and ZX devices based on them) support a varying number of external
interrupt inputs. (External interrupts are not available on any ATxmega devices.) The table below gives
the available external interrupt input pins for ZX devices.

external interrupts are not available on xmega devices.
