9.3.1 Standard setting with easy programming
9.3 Register description
If registers (or bit groups contained in registers) are programmed with invalid values, i.e.
values different from those described in the tables below, the default behavior is chosen
for the related block. Other settings than described in the tables are not allowed.
With the implemented ‘easy programming’, only one bit sets the TV or FM radio standard
with recommended register content. If not suitable however, any of these registers can be
written with other settings. With the rising edge of the bit ACTIVE, some of the registers
02h to 23h are programmed internally with the standard dependent settings according to
Table
Table 11.
Legend: * = default value.
In addition to application specific software settings following general recommendation
should be used (deviating from easy programming values):
Remark: When using alternative ADC sampling frequencies the DTO settings have to be
adapted accordingly.

Legend: * = default value.
