14.25 SPEED_ALARM
A GPS measurement completed and a speed violation occurred. The parameter [0-15] indicates
which Sensor Table was used.
14.26 TIMER
This occurs when a software timer expires. The parameter [0-39] indicates which timer expired.
Timers may be set, examined and read using function calls such as TIMER_set(),
TIMER_clear(), TIMER_checkWakeup(), TIMER_setDuration() and
TIMER_getRemaining(). Note that in making calls to the timer utilities, a particular timer must
be selected. It is important to select a timer with the appropriate type for the intended use. The
types and properties of all timers are shown in Table 14-1.

Volatile
Value and status of these timers are lost when the modem powers
down. These timers should be used for general purpose timing
requirements. On power-up, all Volatile timers are set to disabled.

Non
-
Volatile
Value and status of these timers are stored in NVM. This type of timer is
used when timing data relating to an event or action must be maintained
during power off. When a Non-Volatile timer expires, it does not cause a
wake up of the modem, but does cause a timer event to be sent to the
application on the next power on.

-
Up
Wake-up timers are like nonvolatile timers, except that when a power
down is called, the Real-Time Clock (RTC) is programmed to wake up at
the timer expiration time (if this time is less than the specified power
down interval).

Day
These timers are identical to Wake-Up timers, except that the duration of
the timer is specified as an absolute time of day rather than relative to
the current time. Time-Of-Day Timers always expire within 24 hours.
14.27 TIME_SYNC
The time has been received from a source such as a satellite or GSM and the real-time clock has
been updated to the new time. Parameter one is the value of the change and should be
converted to a signed 32 value to ensure negative adjustments are accounted for.
