10.2 Register bit behavior
Bits and flags for different registers behave differently, depending on their functions. In
principle, bits with same behavior are grouped in common registers.

Description
These bits can be read and written by the microprocessor.
Since they are only used for control, their content is not
influenced by internal state machines.
Example: TimerReload register may be read and written by
the microprocessor. It will also be read by internal state
machines but never changed by them.
These bits can be read and written by the microprocessor.
Nevertheless, they may also be written automatically by
internal state machines.
Example: the Command register changes its value
automatically after the execution of the command.
These registers hold flags which have a value determined by
internal states only.
Example: the ErrorFlag register cannot be written externally
but shows internal states.
These registers are used for control only. They may be written
by the microprocessor but cannot be read. Reading these
registers returns an undefined value.
Example: The TestAnaSelect register is used to determine the
signal on pin AUX however, it is not possible to read its
content.
Where applicable, the values 0 and 1 indicate the expected
logic value for a given bit. Where X is used, any logic value can
be entered
