4. Four-phase complementary non-overlapping pulse output can be obtained subsequently by
writing H'59, H'56, H'95... 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.

If the G3INV, G2INV, G1INV, and G0INV bits in PMR are cleared to 0, values that are the
inverse of the PODR contents can be output.
Figure 11.10 shows the outputs when G3INV and G2INV are cleared to 0, in addition to the
settings of figure 11.9.
