System functions
2.2.1
Power modes
NINA-B50 series modules are capable of operating in different power modes for power consumption
level and wake-up time balance. Consequently, specific parts of the module can be powered off when
they are not needed, and complex wake-up events can be generated from different external and
internal inputs.
NINA-B50 series modules support following power modes:
•
Active
•
Sleep
•
Deep sleep
•
Power down
•
Deep power down
For detailed description of each power mode, see also the NINA-B50 data sheet
2.2.2
Module reset
NINA-B50 series module is reset / rebooted through the
RESET_N
pin:
•
RESET_N
has an internal pull-up resistor setting its default state to high. Setting the pin low
triggers a “hardware reset” of the module.
•
RESET_N
should be driven by either an open-drain or open-collector output or a contact switch.
NINA-B50 series modules can also be reset using other methods. For more information, see also
NINA-B50 data sheet
