This sections provides useful and practical pieces of information
concerning the implementation of the CGM module.
Starting from a ceramic resonator or quartz crystal frequency F
‘refdv’ and ‘synr’ are the decimal content of the REFDV and SYNR
registers respectively, then the MCU bus frequency will simply be:
It is not allowed to synthesize a bus frequency that is lower than the
crystal frequency, as the correct functioning of some internal
