-- SPI: Cache the SPI device in the communication interface. Architecturally, this makes a
-  lot more sense because each ComIF should be responsible for one SPI bus.
-- SPI: Move the empty transfer to update the line polarity to separate function. This means
-  it is not automatically called when calling the setter function for SPI speed and mode.
-  The user should call this function after locking the CS mutex if multiple SPI devices with
-  differing speeds and modes are attached to one bus.

+ * This class has a dual use
+ *
+ * 1) It is used as an IPC method:
+ * It implements a shared memory which can be written and read by different parties
+ *
+ * 2) It is used to define data that is to be downlinked, either periodically or
+ * triggered by an (abstract, not in the sense of fsfw/events) event occuring, ie
+ * data was received from an external source and should be shared with ground.
+ *
+ * Generating a downlinked report is coupled to commiting, as without a commit there is no
+ * change in information to be reported.
+ *
+ * Nominally, the decision to report is done by the set itself, depending on its settings.
+ * If a report is to be forced regardless of these settings, the commitAndReport() functions
+ * are provided which will always generate a report.
+ *
+ * Periodic reports are not tied to a specific tc and are reported as "unrequested". When forcing
+ * a report, optionally a tc can be provided which (logically) triggered the report.
+ *
+ * And, as life is complicated, there is a third set of commits: commitAndReportIfRequested(). Same
+ * as before, but this time, a report is only generated, if the store_address_t is valid. These are
+ * used if at the place where the commit is called, it is not known if there is a request (cf DHB

- * @brief	The DataSetBase class manages a set of locally checked out variables.
- * @details
- * This class manages a list, where a set of local variables (or pool variables)
- * are registered. They are checked-out (i.e. their values are looked
- * up and copied) with the read call. After the user finishes working with the
- * pool variables, he can write back all variable values to the pool with
- * the commit call. The data set manages locking and freeing the data pool,
- * to ensure that all values are read and written back at once.
- *
- * An internal state manages usage of this class. Variables may only be
- * registered before the read call is made, and the commit call only
- * after the read call.
- *
- * If pool variables are writable and not committed until destruction
- * of the set, the DataSet class automatically sets the valid flag in the
- * data pool to invalid (without) changing the variable's value.
- *
- * The base class lockDataPool und unlockDataPool implementation are empty
- * and should be implemented to protect the underlying pool type.
