C8051F060/1/2/3/4/5/6/7 devices include a programmable internal oscillator and an external oscillator
drive circuit. The internal oscillator can be enabled, disabled and calibrated using the OSCICN and
OSCICL registers, as shown in Figure 15.1. The system clock can be sourced by the external oscillator cir-
cuit, the internal oscillator, or a scaled version of the internal oscillator. The internal oscillator's electrical
specifications are given in Table 15.1.
15.1. Programmable Internal Oscillator
All C8051F060/1/2/3/4/5/6/7 devices include a programmable internal 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 Figure 15.2.
OSCICL is factory calibrated to obtain a 24.5 MHz base frequency (f
Electrical specifications for the precision internal oscillator are given in Table 15.1. The programmed inter-
nal oscillator frequency must not exceed 25 MHz. Note that the system clock may be derived from the pro-
grammed internal oscillator divided by 1, 2, 4, or 8, as defined by the IFCN bits in register OSCICN.
