6.6.4 Collective manipulation of TOmn bit
In timer output register m (TOm), the setting bits for all the channels are located in one register in the same way as timer
channel start register m (TSm). Therefore, the TOmn bit of all the channels can be manipulated collectively.
Only the desired bits can also be manipulated by enabling writing only to the TOmn bits (TOEmn = 0) that correspond to
the relevant bits of the channel used to perform output (TOmn).
Figure 6-40. Example of TO0n Bit Collective Manipulation
Writing is done only to the TOmn bit with TOEmn = 0, and writing to the TOmn bit with TOEmn = 1 is ignored.
TOmn (channel output) to which TOEmn = 1 is set is not affected by the write operation. Even if the write operation is
done to the TOmn bit, it is ignored and the output change by timer operation is normally done.
