6.5.3
Note:
RC Control Register High (RCCRH)
Reset value: 1111 1111 (FFh)
Bits 7:0 = CR[9:2] RC Oscillator Frequency Adjustment bits
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.
CR9
These bits must be written immediately after reset to adjust the RC oscillator
frequency. The application can store the correct value for each voltage range in Flash
memory and write it to this register at start-up.
00h = maximum available frequency
FFh = lowest available frequency
These bits are used with the CR[1:0] bits in the RCCRL register. Refer to
