These bits, as well as CR[1:0] bits in the SICSR register must be written
immediately after reset to adjust the RC oscillator frequency and to obtain the
required accuracy. The application can store the correct value for each voltage
range in Flash memory and write it to this register at startup.
00h = maximum available frequency
FFh = lowest available frequency
Note: To tune the oscillator, write a series of different values in the register until the

starting with 80h.
