Register Information

Texas Instruments TCA9548A register information is defined in the following structures:

• ::picolibrary::Texas_Instruments::TCA9548A::Control

The following constants are defined in register information structures:

• RESET: the register’s reset value

Device Addressing

The ::picolibrary::Texas_Instruments::TCA9548A::Address_Numeric type alias is used to store a Texas Instruments TCA9548A device address in numeric (right justified) format. See the ::picolibrary::I2C::Device_Address_Numeric documentation for more information.

The ::picolibrary::Texas_Instruments::TCA9548A::Address_Transmitted type alias is used to store a Texas Instruments TCA9548A device address in transmitted (left shifted) format. See the ::picolibrary::I2C::Device_Address_Transmitted documentation for more information.

Driver

The ::picolibrary::Texas_Instruments::TCA9548A::Driver Texas Instruments TCA9548A driver template class is used to interact with a Texas Instruments TCA9548A.

• To read the Control register, use the ::picolibrary::Texas_Instruments::TCA9548A::Driver::read_control() member function.
• To write to the Control register, use the ::picolibrary::Texas_Instruments::TCA9548A::Driver::write_control() member function.

::picolibrary::Texas_Instruments::TCA9548A::Driver automated tests are defined in the test/automated/picolibrary/texas_instruments/tca9548a/driver/main.cc source file.

The ::picolibrary::Testing::Automated::Texas_Instruments::TCA9548A::Mock_Driver mock Texas Instruments TCA9548A driver class is available if the PICOLIBRARY_ENABLE_AUTOMATED_TESTING project configuration option is ON. The mock is defined in the include/picolibrary/testing/automated/texas_instruments/tca9548a.h/source/picolibrary/testing/automated/texas_instruments/tca9548a.cc header/source file pair.

The ::picolibrary::Testing::Interactive::Texas_Instruments::TCA9548A::scan() interactive test helper is available if the PICOLIBRARY_ENABLE_INTERACTIVE_TESTING project configuration option is ON. The interactive test helper is defined in the include/picolibrary/testing/interactive/texas_instruments/tca9548a.h/source/picolibrary/testing/interactive/texas_instruments/tca9548a.cc header/source file pair.

The ::picolibrary::Texas_Instruments::TCA9548A::Caching_Driver Texas Instruments TCA9548A caching driver template class adds register caching to ::picolibrary::Texas_Instruments::TCA9548A::Driver.

• To reset all cached register values, use the ::picolibrary::Texas_Instruments::TCA9548A::Caching_Driver::reset_cache() member function.
• To write to the Control register, use the ::picolibrary::Texas_Instruments::TCA9548A::Caching_Driver::write_control() member function.
• To get the cached Control register value, use the ::picolibrary::Texas_Instruments::TCA9548A::Caching_Driver::control() member function.

::picolibrary::Texas_Instruments::TCA9548A::Caching_Driver automated tests are defined in the test/automated/picolibrary/texas_instruments/tca9548a/caching_driver/main.cc source file.

The ::picolibrary::Testing::Automated::Texas_Instruments::TCA9548A::Mock_Caching_Driver mock Texas Instruments TCA9548A caching driver class is available if the PICOLIBRARY_ENABLE_AUTOMATED_TESTING project configuration option is ON. The mock is defined in the include/picolibrary/testing/automated/texas_instruments/tca9548a.h/source/picolibrary/testing/automated/texas_instruments/tca9548a.cc header/source file pair.

Bus Multiplexer Aligner

The ::picolibrary::Texas_Instruments::TCA9548A::Bus_Multiplexer_Aligner template class is a nullary functor that is intended to be used as a ::picolibrary::I2C::Device instance’s bus multiplexer aligner. ::picolibrary::Texas_Instruments::TCA9548A::Bus_Multiplexer_Aligner automated tests are defined in the test/automated/picolibrary/texas_instruments/tca9548a/bus_multiplexer_aligner/main.cc source file.
