Figure 12.9 shows an example in which pulse output is used for four-phase complementary non-
overlapping pulse output.
1. Set up the TPU channel to be used as the output trigger channel so that TGRA and TGRB are
2. Write H'FF in P1DDR and NDERH, and set the G3CMS1, G3CMS0, G2CMS1, and G2CMS0
3. The timer counter in the TPU channel starts. When a compare match with TGRB occurs,
output compare registers. Set the trigger period in TGRB and the non-overlap margin in
TGRA, and set the counter to be cleared by compare match B. Set the TGIEA bit in TIER to 1
to enable the TGIA interrupt.
bits in PCR to select compare match in the TPU channel set up in the previous step to be the
output trigger. Set the G3NOV and G2NOV bits in PMR to 1 to select non-overlapping output.
Write output data H'95 in NDRH.
outputs change from 1 to 0. When a compare match with TGRA occurs, outputs change from 0
