default value
Before sending internal settings the microcontroller should
check whether or not the SAA2520 is ready-to-receive.
However, this does not apply for the transfer of internal
settings to end a transfer of allocation information.

The bit rate index indicates the bit rate of the sub-band
signal in units of 32 kbits/s. bit rate index 0000 indicates
the ‘free format’ condition. bit rate 1111 is illegal and
should not be found.
The coding of the sample frequency indication is equal
to the one in the internal settings.
