Datasheet

• Modulo VCO frequency divider Phase/Frequency detector
• Integrated loop filter
• Internal reference clock generator
• Slow clock with nine trim bits for accuracy
• Fast clock with four trim bits
• Can be used to control the FLL
• Either the slow or the fast clock can be selected as the clock source for the MCU
• Can be used as a clock source for other on-chip peripherals
• External clock from the Crystal Oscillator (XOSC)
• Can be used to control the FLL and/or the PLL
• Can be selected as the clock source for the MCU
• External clock monitor with reset request capability
• Lock detector with interrupt request capability for use with the PLL
• Auto Trim Machine (ATM) for trimming both the slow and fast internal reference clocks
• Multiple clock source options available for most peripherals
