•
Frequency-locked loop (FLL)
— 0.2% resolution using internal 32 kHz reference
— 2% deviation over voltage and temperature using internal 32 kHz reference
— Internal or external reference can be used to control the FLL
Phase-locked loop (PLL)
— Voltage-controlled oscillator (VCO)
— Modulo VCO frequency divider
— Phase/Frequency detector
— Integrated loop filter
— Lock detector with interrupt capability
Internal reference clock
— Nine trim bits for accuracy
— Can be selected as the clock source for the MCU
External reference clock
— Control for external oscillator
— Clock monitor with reset capability
— Can be selected as the clock source for the MCU
Reference divider is provided
Clock source selected can be divided down by 1, 2, 4, or 8
BDC clock (MCGLCLK) is provided as a constant divide by 2 of the DCO output whether in an
FLL or PLL mode.
