8.2.2.2 MFINTOSC
The module provides two (500 kHz and 31.25 kHz) constant clock outputs. These clocks are digital divisors of the HFINTOSC clock. Dynamic divider logic is used to provide constant MFINTOSC clock rates for all settings of HFINTOSC.
The MFINTOSC cannot be used to drive the system but it is used to clock certain modules such as the Timers and WWDT.
