In the write mode, the data transfer between the TEA5777 (slave) and the microcontroller
(master) is byte oriented.
In the read mode, the data transfer from slave to master is bit oriented.
Remark: For writing to the PLL, it is necessary to write both the first and second data
byte. Only after completing the data transfer of data byte 2 is the PLL word copied into the
PLL register.
