PPG output operations
Setting 16-bit timer mode control register 00 (TMC00) and capture/compare control register 00 (CRC00) as shown
in Figure 6-30 allows operation as PPG (Programmable Pulse Generator) output.
Setting
The basic operation setting procedure is as follows.
<1>
Set the CRC00 register (see Figure 6-30 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 6-30 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 6-30 for the set value).
Caution
Changing the CRC0n0 setting during TM00 operation may cause a malfunction. To change the
setting, refer to 6.5 Cautions Related to 16-Bit Timer/Event Counter 00 (17) Changing compare
register during timer operation.
Remarks 1. For the setting of the TO00 pin, see 6.3 (5) Port mode register 2 (PM2) and port mode control
register 2 (PMC2).
2. For how to enable the INTTM000 interrupt, see CHAPTER 10 INTERRUPT FUNCTIONS.
3. n = 0 or 1
In the PPG output operation, rectangular waves are output from the TO00 pin with the pulse width and the cycle
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.
