Bits 7:0 CR[9:2] RC Oscillator Frequency Adjustment Bits
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
correct frequency is reached. The fastest method is to use a dichotomy
starting with 80h.

Bits 6:5 CR[1:0] RC Oscillator Frequency Adjustment bits
These bits, as well as CR[9:2] bits in the RCCR register must be written
immediately after reset to adjust the RC oscillator frequency and to obtain the
required accuracy. Refer to Section 6.2 on page 28.
Bits 4:3 Reserved, must be kept cleared.
Bits 2:0 System Integrity bits. Refer to Section 7.4 on page 43.
