11.7.4
When the internal clock is changed, the changeover may source FRC to increment. This depends
on the time at which the clock is switched (bits CKS1 and CKS0 are rewritten), as shown in table
11.3.
When an internal clock is used, the FRC clock is generated on detection of the falling edge of the
internal clock scaled from the system clock (φ). If the clock is changed when the old source is high
and the new source is low, as in case no. 3 in table 11.3, the changeover is regarded as a falling
edge that triggers the FRC clock, and FRC is incremented. Switching between an internal clock
and external clock can also source FRC to increment.
