!    This file also defines EXT_STANDBY_T0_THRESHOLD, a threshold on
!    remaining time till the next timer 0 interrupt under which the mote
!    should sleep in ext standby rather than power save. This is only
!    important when not using the internal oscillator.  Wake up from power
!    save takes 65536 cycles (6 cycles for ext standby), which is, e.g.,
!    ~9.4ms at 7Mhz.
