Figure 12: Clock System Overview
13.1.4 Oscillators and clocks
The CC2430 has one internal system clock.
The source for the system clock can be either
a 16 MHz RC oscillator or a 32 MHz crystal
oscillator. Clock control is performed using the
CLKCON SFR register.
The system clock also feeds all 8051
peripherals (as described in section 6).
13.1.4.1
Oscillators
Figure 12 gives an overview of the clock
system with available clock sources.
There is also one 32 kHz clock source that can
either be a RC oscillator or a crystal oscillator,
also controlled by the CLKCON register.
The choice of oscillator allows a trade-off
between high-accuracy in the case of the
crystal oscillator and low power consumption
when the RC oscillator is used. Note that
operation of the RF transceiver requires that
the 32 MHz crystal oscillator is used.
Two high frequency oscillators are present in
the device:
