RTO0 to 5 ON/OFF control is practically taken by the macro in the microprocessor mounted on the board.
So, it is necessary to configure registers for functions employed by the macro. “Table 4-2 Functions
employed by the motor driving macro” shows the functions employed.
The registers used for the 16-bit free-run timer are as shown in “Figure 4-5 Timer control registers”. A
description of the registers and their setting values in the sample program are as described in “Table 4-3
Description of the timer control registers and setting values”. For more information of the registers, refer
to the microcontroller hardware manual.

Timer in which an up/down counter is used.
This counter is used to configure the output compare function.
Used to make comparisons with the value of the free-run timer,
and the resulting values are used to turn on/off RTO0 to 5.
