RTCNT Operation at Internal Clock Source Switchover: Switching internal clock sources may
cause RTCNT to increment, depending on the switchover timing. Table 6.10 shows the relation
between the time of the switchover (by writing to bits CKS2 to CKS0) and the operation of
RTCNT.
The RTCNT input clock is generated from the internal clock source by detecting the falling edge
of the internal clock. If a switchover is made from a high clock source to a low clock source, as in
case No. 3 in table 6.10, the switchover will be regarded as a falling edge, an RTCNT clock pulse
will be generated, and RTCNT will be incremented.
