MAX-M10M-Integration manual
• Controlled software reset terminates all running processes in an orderly manner. Once the
system is idle, restarts the receiver operation, reloads its configuration and starts to acquire
and track GNSS satellites.
• Controlled software reset (GNSS only) only restarts the GNSS tasks, without reinitializing the
full system or reloading any stored configuration.
• Hardware reset (after shutdown) uses the on-chip watchdog to reset the receiver after
shutdown.
• Controlled GNSS stop stops all GNSS tasks. The receiver is not restarted, but stops any GNSS-
related processing.
• Controlled GNSS start starts all GNSS tasks.
Table 21 below contains an overview of the different reset types and the data that is cleared.

3.5 Security
The security concept of MAX-M10M covers:
• the integrity of the receiver
• communication between the receiver and the GNSS satellites
Some security functions monitor and detect threats and report them to the host system. Other
functions mitigate threats and allow the receiver to operate normally.
3.5.1 Configuration locking
The receiver configuration can be locked so that further changes are no longer possible. The
configuration can be locked by setting the configuration item CFG-SEC-CFG_LOCK to "true". This
item can be set in the same way as all other configuration items on various layers.
If the configuration lock is set in BBR, it remains locked until the BBR is cleared. To test the
function, set it in the RAM configuration layer. After the receiver's power cycle, the information
in this layer is lost and the configuration lock is not set anymore.
3.6 Power management
u-blox receivers support different operating modes. These modes represent strategies of controlling
the acquisition and tracking engines to achieve either the best possible performance or good
performance with reduced power consumption.
3.6.1 Continuous mode
MAX-M10M uses dedicated signal processing engines optimized for signal acquisition and tracking.
The acquisition engine actively searches for and acquires signals during cold starts or when
insufficient signals are available during navigation. The tracking engine continuously tracks and
