CAUTION
The peripheral - I/O multiplexing implemented in the 280x devices prevents all
available peripherals from being used at the same time. This is because more than
one peripheral function may share an I/O pin. It is, however, possible to turn on the
clocks to all the peripherals at the same time, although such a configuration is not
useful. If this is done, the current drawn by the device will be more than the numbers
specified in the current consumption tables.
