6.1.2 STOP – Stop Navigation
Commands PCM3292 to stop navigating and enter the idle state. While in idle state, the
PCM3292 receiver doesn’t navigate but still accept commands., less power is consumed in
the idle state than in the navigation state; however, remarkably more than in the power-down
mode. This command also stores the “LastKnownGood” fix, ephemeris and almanac data in
flash memory.
$PFST,STOP,<1|0>
<1|0> 1 to save, 0 not to save “LastKnownGood” fix, ephemeris
and almanac data to flash memory.
5.1.2 PWRDOWN – PCM3292 Sleep Mode
Commands PCM3292 to sleep mode.
Using the sleep mode is recommended when navigation isn’t needed. PCM3292 consumes
remarkably little power in the sleep mode and still re-acquires the navigation fix quickly
after waking up.
PCM3292 wakes up from the sleep mode when the timeout has expired. If the receiver was
navigating when the PWRDOWN command was given, navigation will restart automatically
after waking up from the sleep mode.
