periods) and a slave channel (timer that operates in accordance with the master channel), and several rules must be
observed when using this function.
7.6.2 Basic rules of combination-operation function
284
The timer array unit consists of several channels and has a single-operation function that allows each channel to
The single-operation function can be used for any channel, regardless of the operation mode of the other channels.
The combination-operation function is realized by combining a master channel (reference timer that mainly counts
The basic rules of using the combination-operation function are as follows.
(1) Only an even channel (channel 0, 2, 4, etc.) can be set as a master channel.
(2) Any channel, except channel 0, can be set as a slave channel.
(3) The slave channel must be lower than the master channel.
(4) Two or more slave channels can be set for one master channel.
(5) When two or more master channels are to be used, slave channels with a master channel between them may
(6) The operating clock for a slave channel in combination with a master channel must be the same as that of the
(7) A master channel can transmit INTTMmn (interrupt), start software trigger, and count clock to the lower
(8) A slave channel can use the INTTMmn (interrupt), start software trigger, and count clock of the master channel,
(9) A master channel cannot use the INTTMmn (interrupt), start software trigger, and count clock from the other
(11) During a counting operation, the TSmn bit of all channels that operate in combination or only the master
(12) To stop the channels in combination simultaneously, the TTmn bit of the channels in combination must be set
Remark
(10) To simultaneously start channels that operate in combination, the TSmn bit of the channels in combination
Example: If channel 2 of the TAU0 is set as a master channel, channel 3 or those that follow (channels 3, 4,

Example: If channels 0 and 4 of the TAU0 are set as master channels, channels 1 to 3 can be set as the
master channel. The CKS bit (bit 15 of the TMRmn register) of the slave channel that operates in combination
with the master channel must be the same value as that of the master channel.
