6.4.2 PPG output operations
in Figure 6-13 allows operation as PPG (Programmable Pulse Generator) output.
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 6-13 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 6-13 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 6-13 for the set value).
Caution To change the value of the duty factor (the value of the CR010 register) during operation, see
Remarks 1. For the setting of the TO00 pin, see 6.3 (5) Port mode register 0 (PM0).
In the PPG output operation, rectangular waves are output from the TO00 pin with the pulse width and the cycle
