To avert contention between initialization of the up-counter due to the changed value of the bit
and counting operation, change the CKS1 bit from 0 to 1 within the 32KOVI interrupt routine.
Timing of the operation of changing the CKS1 bit when EXCKSN=0 is shown in figure 17.3.
Note that generation of the 32KOVI interrupt will fail once if there is a conflict between the
timing with which the CKS1 bit is changed from 1 to 0 and the value of TCNT32K3 becomes
H'3B. This is shown in figure 17.4.
