CHAPTER 6 TIMER ARRAY UNIT
6.4.4 Collective manipulation of TOpq bits
In the TOp register, the setting bits for all the channels are located in one register in the same way as the TSp register
(channel start trigger). Therefore, TOpq of all the channels can be manipulated collectively. Only specific bits can also be
manipulated by setting the corresponding TOEpq = 0 to a target TOpq (channel output).

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

(Caution and Remark are given on the next page.)
Two or more TOpq output can
be changed simultaneously
Output does not change
when value does not
change
Writing to TOp bit
is ignored when TOEpq
