easily confirmed by executing the read instruction (RD instruction) of TC3DRB.
Loading the contents of up counter is not synchronized with counting up. The contents
of over flow (FFH) and 00H can not be loaded correctly. It is necessary to consider the
count cycle.
In this mode, the internal clock is used for counting up. The contents of TC3DRA are
The current contents of up counter are loaded into TC3DRB by setting
