Oscillator (OSC)
25.1 Introduction
NOTE
For the chip-specific implementation details of this module's
instances see the chip configuration chapter.
The OSC module is a crystal oscillator. The module, in conjunction with an external
crystal or resonator, generates a reference clock for the MCU.
25.2 Features and Modes
Key features of the module are:
⢠Supports 32 kHz crystals (Low Range mode)
⢠Supports 3â8 MHz, 8â32 MHz crystals and resonators (High Range mode)
⢠Automatic Gain Control (AGC) to optimize power consumption in high frequency
ranges 3â8 MHz, 8â32 MHz using low-power mode
⢠High gain option in frequency ranges: 32 kHz, 3â8 MHz, and 8â32 MHz
⢠Voltage and frequency filtering to guarantee clock frequency and stability
⢠Optionally external input bypass clock from EXTAL signal directly
⢠One clock for MCU clock system
⢠Two clocks for on-chip peripherals that can work in Stop modes
Functional Description describes the module's operation in more detail.
