Figure 15.5 shows an example in which pulse output is used for cyclic 5-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 to NDERH, and set bits G3CMS1, G3CMS0, G2CMS1, and G2CMS0 in PCR to

contents are transferred to PODRH and output. The TGIA interrupt handling routine writes the
next output data (H'C0) in NDRH.
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.
