14. Oscillators
C8051F340/1/2/3/4/5/6/7/8/9 devices include a programmable internal high-frequency oscillator, a pro-
grammable internal low-frequency oscillator (C8051F340/1/2/3/4/5/8/9), an external oscillator drive circuit,
and a 4x Clock Multiplier. The internal high-frequency and low-frequency oscillators can be enabled/dis-
abled and adjusted using the special function registers, as shown in Figure 14.1. The system clock (SYS-
CLK) can be derived from either of the internal oscillators, the external oscillator circuit, or the 4x Clock
Multiplier divided by 2. The USB clock (USBCLK) can be derived from the internal oscillator, external oscil-
lator, or 4x Clock Multiplier. Oscillator electrical specifications are given in Table 14.1.
