20. Oscillators and Clock Selection
C8051T610/1/2/3/4/5/6/7 devices include a programmable internal high-frequency oscillator and an exter-
nal oscillator drive circuit. The internal high-frequency oscillator can be enabled/disabled and calibrated
using the OSCICN and OSCICL registers, as shown in Figure 20.1. The system clock can be sourced by
the external oscillator circuit or the internal oscillator. The internal oscillator also offers a selectable post-
scaling feature.

20.1. System Clock Selection
The CLKSL0 bit in register CLKSEL selects which oscillator source is used as the system clock. CLKSL0
must be set to 1 for the system clock to run from the external oscillator; however the external oscillator may
still clock certain peripherals (timers, PCA) when the internal oscillator is selected as the system clock. The
system clock may be switched on-the-fly between the internal oscillator and external oscillator, so long as
the selected clock source is enabled and running.
The internal high-frequency oscillator requires little start-up time and may be selected as the system clock
immediately following the register write which enables the oscillator. The external RC and C modes also
typically require no startup time.
