3 Configuration management
Configuration settings can be modified with UBX configuration messages. The modified settings remain effective
until power-down or reset. If these settings have been stored in battery-backup RAM, then the modified
configuration will be retained, as long as the backup battery supply is not interrupted.
4 Electrical specification
The limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress
above one or more of the limiting values may cause permanent damage to the device. These are stress
ratings only, and operation of the device at these or at any other conditions above those given in the
characteristics sections of the specification is not implied. Exposure to these limits for extended periods
may affect device reliability.
Where application information is given, it is advisory only and does not form part of the specification. For
more information, see the SAM-M8Q Hardware Integration Manual [1].

Table 6: Absolute maximum ratings
Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.
These are stress ratings only. The product is not protected against overvoltage or reversed
voltages. If necessary, voltage spikes exceeding the power supply voltage specification, given in
table above, must be limited to values within the specified boundaries by using appropriate
protection diodes.
