Figure 17.18
Figure 17.18 shows an Example of One-Shot Waveform Output Operation in PWM2 Mode (Count is Started by
TRCTRG Input).
After the CTS bit in the TRCMR register is set to 1 (count starts), the increment is started at the rising edge of
TRCIOA/TRCTRG, and the counter is changed to 0000h by a compare match with the TRCGRA register, the
count operation is stopped, and a one-shot waveform is output under the following conditions.
• Bits TCEG1 and TCEG0 in the TRCCR2 register are set to 10b (falling edge) to set the falling edge of the
• The CSTP bit in the TRCCR2 register is set to 1 (increment stops) to stop the increment when a compare
• The CCLR bit in the TRCCR1 register is set to 1 (TRCCNT counter is cleared by input capture/compare
• The TOB bit in the TRCCR1 register is set to 0 (output value is low) to set the initial value of the output level
