Read = 0; Write = Don’t Care
Internal Oscillator Coarse Calibration Bits.
These bits determine the internal oscillator period. When set to 0000000b, the
internal oscillator operates at its slowest setting. When set to 1111111b, the inter-
nal oscillator operates at its fastest setting. The reset value is factory calibrated
to generate an internal oscillator frequency of 24 MHz.
