Reset Source

The ::microlibrary::Microchip::megaAVR0::Reset_Source class holds a Microchip megaAVR 0-series microcontroller’s reset source(s).

• To get the RSTCTRL peripheral RSTFR value, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::rstctrl_rstfr() member function.
• To check if a power-on reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_power_on_reset() member function.
• To check if a brown-out reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_brown_out_reset() member function.
• To check if an external reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_external_reset() member function.
• To check if a watchdog reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_watchdog_reset() member function.
• To check if a software reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_software_reset() member function.
• To check if a UPDI reset has occurred, use the ::microlibrary::Microchip::megaAVR0::Reset_Source::is_updi_reset() member function.

::microlibrary::Microchip::megaAVR0::Reset_Source automated tests are defined in the test-automated-microlibrary-microchip-megaavr0-reset_source automated test executable’s main.cc source file.

Reset Controller

The ::microlibrary::Microchip::megaAVR0::Reset_Controller reset controller class is used to interact with a Microchip megaAVR 0-series microcontroller’s RSTCTRL peripheral.

• To get the reset source(s), use the ::microlibrary::Microchip::megaAVR0::Reset_Controller::reset_source() member function.
• To clear the reset source(s), use the ::microlibrary::Microchip::megaAVR0::Reset_Controller::clear_reset_source() member function.
• To initiate a software reset, use the ::microlibrary::Microchip::megaAVR0::Reset_Controller::initiate_software_reset() member function.

::microlibrary::Microchip::megaAVR0::Reset_Controller automated tests are defined in the test-automated-microlibrary-microchip-megaavr0-reset_controller automated test executable’s main.cc source file.

The ::microlibrary::Testing::Automated::Microchip::megaAVR0::Mock_Reset_Controller mock reset controller class is available if MICROLIBRARY_TARGET is DEVELOPMENT_ENVIRONMENT. The mock is defined in the microlibrary/testing/automated/microchip/megaavr0/reset.h/microlibrary/testing/automated/microchip/megaavr0/reset.cc header/source file pair.
