 ### Notes
 - The `SPIBus` object must be shared by all slaves on the same bus. Do not create multiple instances of the class `SPIBus` for each sensor.
-- But each slave can have different configurations
-- SPITransactions must be scoped (if not, in the first example, the bus may be configured for *slave 2* before the operations with *slave 1* are performed)
+- Each slave can use a different `SPIBusConfig`
+- SPITransactions must be scoped (much like mutexes). If not, in the first example, the bus may be configured for *slave 2* before the operations with *slave 1* are performed.
 - Access through `SPIBusInterface` (second example) is discouraged due to its complexity and because it is error-prone (easy to forget to configure / select / deselect). But it may be necessary in some cases (sensors with non-standard SPI implementation)
 - Operations on the same bus must be synchronized between multiple threads. It is strongly recommended to perform operations from a single thread to avoid synchronization problems.
