EVK-M10QSAM - User guide
shows the configuration window for selecting the receiver power mode and configuring
the position update period. For the On/Off power mode, the position update period is defined with
the
CFG-PM-POSUPDATEPERIOD
. To maintain the configuration during an inactive state, save it
both in the RAM and BBR layer.
The CFG-PM-OPERATEMODE configuration is applied last after other required power mode
configuration items are defined in the CFG-PM group.

9.4.1 Backup modes
SAM-M10Q supports two backup modes: hardware backup mode and software standby mode.
•
Hardware backup mode:
In this mode, other supplies except the backup supply (V_BCKP) are
turned off. On the EVK-M10QSAM, this is achieved by turning off the main power supply of the
EVK either by removing the USB cable or the 5.0 V supply from the 14-pin connector.
•
Software standby mode:
In this mode, the receiver executes little or no system activity. To
wake the receiver up from the software standby mode, the wakeup source can be configured in
UBX-RXM-PMREQ
message. The available wakeup sources are EXTINT and UART RxD signals.
The duration in the UBX-RXM-PMREQ message can be set to 0 for putting the receiver to
software standby mode indefinitely until a signal is detected from the configured wakeup source.
In addition, ensure that the force option is selected.
The RAM memory is cleared in the software standby mode and in the off state of PSMOO. To
maintain the configuration during the inactive state, save it both in the RAM and BBR layer.
