20.2. Programmable Internal High-Frequency (H-F) Oscillator
All C8051T610/1/2/3/4/5/6/7 devices include a programmable internal high-frequency oscillator that
defaults as the system clock after a system reset. The internal oscillator period can be adjusted via the
OSCICL register as defined by SFR Definition 20.2.
On C8051T610/1/2/3/4/5/6/7 devices, OSCICL is factory calibrated to obtain a 24.5 MHz base frequency.
The system clock may be derived from the programmed internal oscillator divided by 1, 2, 4, or 8, as
defined by the IFCN bits in register OSCICN. The divide value defaults to 8 following a reset.

These bits determine the internal oscillator period. When set to 0000000b, the H-F
oscillator operates at its fastest setting. When set to 1111111b, the H-F oscillator
operates at its slowest setting. The reset value is factory calibrated to generate an
internal oscillator frequency of 24.5 MHz.
