Frequency-locked loop (FLL) is trimmable for accuracy
— 0.2% resolution using internal 32kHz reference
— 2% deviation over voltage and temperature using internal 32kHz reference
Internal or external reference clocks up to 5MHz can be used to control the FLL
— 3 bit select for reference divider is provided
Internal reference clock has 9 trim bits available
Internal or external reference clocks can be selected as the clock source for the MCU
Whichever clock is selected as the source can be divided down
— 2 bit select for clock divider is provided
Control signals for a low power oscillator as the external reference clock are provided
— HGO, RANGE, EREFS, ERCLKEN, EREFSTEN
FLL Engaged Internal mode is automatically selected out of reset
is the ICS block diagram.
– Allowable dividers are: 1, 2, 4, 8
– BDC clock is provided as a constant divide by 2 of the DCO output
