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.
9.3.1 Standard setting with easy programming
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, the registers 02h to 23h
are programmed internally with the standard dependent settings according to Table 13.
The content of registers with address 24h and higher is untouched.
