Section 12 Programmable Pulse Generator (PPG)
12.4.3
Figure 12.5 shows an example in which pulse output is used for cyclic five-phase pulse output.
1. Set up TGRA in TPU which is used as the output trigger to be an output compare register. Set
2. Write H'F8 in P1DDR and NDERH, and set the G3CMS1, G3CMS0, G2CMS1, and G2CMS0
3. The timer counter in the TPU channel starts. When compare match A occurs, the NDRH
4. Five-phase pulse output (one or two phases active at a time) can be obtained subsequently by

writing H'40, H'60, H'20, H'30, H'10, H'18, H'08, H'88... at successive TGIA interrupts.
If the DTC or DMAC is set for activation by the TGIA interrupt, pulse output can be obtained
without imposing a load on the CPU.
