These 3 bits are not used and should be set to logic 0.
System clock frequency select.
These 2 bits select the frequency of the system clock;
see Table 49.
System clock output on/off.
SYSOUT = 1, enables the output of a system (or master)
clock signal at pin SYSCLK. SYSOUT = 0, the output will be off, thereby improving EMC
performance.
Serial output format.
I

SFORM = 1, selects an MSB-aligned, MSB-first output format,
i.e. a level change at the word select pin indicates the beginning of a new audio sample.
I

SFORM = 0, selects the standard I

SOUT = 1, enables the output of serial audio data (2 pins) plus
serial bit clock and word select in a format determined by the I

SFORM bit.
The TDA9874H then is an I
