Main Oscillator Connections
Main Oscillator Startup Time
Main Oscillator Control
The Clock Generator integrates a Main Oscillator that is designed for a 3 to 20 MHz fundamental
crystal. The typical crystal connection is illustrated in
required for crystals with frequencies lower than 8 MHz. For further details on the electrical char-
acteristics of the Main Oscillator, see the section “DC Characteristics” of the product datasheet.
The startup time of the Main Oscillator is given in the DC Characteristics section of the product
datasheet. The startup time depends on the crystal frequency and decreases when the fre-
quency rises.
To minimize the power required to start up the system, the main oscillator is disabled after reset
and slow clock is selected.
The software enables or disables the main oscillator so as to reduce power consumption by
clearing the MOSCEN bit in the Main Oscillator Register (CKGR_MOR).
