16.3.13 A/D Conversion Start Trigger Setting Function
Timer RD can generate the A/D conversion start trigger signal by setting the timer RD A/D
conversion start trigger control register (TRDADCR) or bits ADEG and ADTRG in the timer RD
function control register (TRDFCR).
Figures 16.58 and 16.59 show examples of the A/D conversion trigger signal generation in
complementary PWM mode.
