Multi-Purpose Clock Generator (S08MCGV1)
8.1.1 Features
Key features of the MCG module are:
⢠Frequency-locked loop (FLL)
â 0.2% resolution using internal 32-kHz reference
â 2% deviation over voltage and temperature using internal 32-kHz reference
â Internal or external reference can be used to control the FLL
⢠Phase-locked loop (PLL)
â Voltage-controlled oscillator (VCO)
â Modulo VCO frequency divider
â Phase/Frequency detector
â Integrated loop ï¬lter
â Lock detector with interrupt capability
⢠Internal reference clock
â Nine trim bits for accuracy
â Can be selected as the clock source for the MCU
⢠External reference clock
â Control for external oscillator
â Clock monitor with reset capability
â 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.
