that correspond to the count values preset in 16-bit timer capture/compare register 010 (CR010) and in 16-bit timer
capture/compare register 000 (CR000), respectively.

Setting 16-bit timer mode control register 00 (TMC00) and capture/compare control register 00 (CRC00) as shown
The basic operation setting procedure is as follows.
<1> Set the CRC00 register (see Figure 6-29 for the set value).
<2> Set any value to the CR000 register as the cycle.
<3> Set any value to the CR010 register as the duty factor.
<4> Set the TOC00 register (see Figure 6-29 for the set value).
<5> Set the count clock by using the PRM00 register.
<6> Set the TMC00 register to start the operation (see Figure 6-29 for the set value).
Caution Changing the CRC0n0 setting during TM00 operation may cause a malfunction. To change the
