+## HAL

+- 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.
+- SPI: Getter functions for SPI speed and mode.
+- I2C: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1.
