The output trigger ITU channel is set up so that GRA and GRB are output compare registers and the
counter will be cleared by compare match B. The TPC output trigger period is set in GRB. The non-
overlap margin is set in GRA. The IMIEA bit is set to 1 in TIER to enable IMFA interrupts.
H'FF is written in PBDDR and NDERB, and bits G3CMS1, G3CMS0, G2CMS1, and G2CMS0 are set
in TPCR to select compare match in the ITU channel set up in step 1 as the output trigger.
Bits G3NOV and G2NOV are set to 1 in TPMR to select non-overlapping output. Output data H'95 is
written in NDRB.
The timer counter in this ITU channel is started. When compare match B occurs, outputs change from
1 to 0. When compare match A occurs, outputs change from 0 to 1 (the change from 0 to 1 is delayed
by the value of GRA). The IMFA interrupt service routine writes the next output data (H'65) in NDRB.
Four-phase complementary non-overlapping pulse output can be obtained by writing H'59, H'56, H'95…
at successive IMFA interrupts. If the DMAC is set for activation by this interrupt, pulse output can be
obtained without loading the CPU.
