In some instances it is desirable that the configuration is
derived from OTP cells and not from user-configurable
registers. It is therefore possible to pre-define the following
features using the OTP facility:

The selection of the mode for factory defaults is made by
setting the factory default OTP cell bit MMFD.
Table 21 Factory default bit MMFD
The operation can be shown as a switch that selects
between two sources of data (see Fig.42). When the OTP
defaults are selected, changing the default values via the
interface is not possible.
