Pin configuration of the serial data interface:
Table 26.
The "PS"-pin (Protocol Select) determines which communication protocol is used for
communication between the microcontroller and the TDA7528. The information is not latched,
so any level change at this pin immediately affects the protocol used by the TDA7528.

represent three groups of addresses. The information is not latched, so any level change at
this pin immediately affects the address used by the TDA7528.
