For lowest current consumption in this mode, all I/O
pins should be either at V
circuitry drawing current from the I/O pin and the
comparators, and V
that are hi-impedance inputs should be pulled high or
low externally to avoid switching currents caused by
floating inputs. The T0CKI input should also be at V

contribution from on chip pull-ups on PORTB should be
considered.
