TDA 5150 Functional Description
2.5
Digital Control (SFR Registers)
2.5.1 SFR Register List
The SFRs (Special Function Registers) are used to configure TDA 5150 and to read out
certain information e.g. the transmitter status.
There are complete SFRs, as well as register bits in SFRs, called “Reserved”. These
SFRs and register bits used in the production process. The SFRs and bits have to be
configured with their default value as shown in the Chapter 2.5.2 SFR Detailed
