6.6.4 Collective manipulation of TO0n bit
In timer output register 0 (TO0), the setting bits for all the channels are located in one register in the same way as timer
channel start register 0 (TS0). Therefore, the TO0n bit of all the channels can be manipulated collectively.
Only the desired bits can also be manipulated by enabling writing only to the TO0n bits (TOE0n = 0) that correspond to
the relevant bits of the channel used to perfor0 output (TO0n).

Writing is done only to the TO0n bit with TOE0n = 0, and writing to the TO0n bit with TOE0n = 1 is ignored.
TO0n (channel output) to which TOE0n = 1 is set is not affected by the write operation. Even if the write operation is
done to the TO0n bit, it is ignored and the output change by timer operation is normally done.
