• The trigger edge for the external input signal can be selected from the three types: rising edge, falling
edge, and both edges. Also, there are registers that indicate whether the trigger edge is a rising edge or a
falling edge.
• Four input captures can be used independently.
• An interrupt can be generated when a valid edge of an external input signal is detected.
●
8/16-bit PPG timer (×8)
• The PPG timer 0 is used to provide the PPG signal for the waveform generator. For more information on
PPG timer 0, see "CHAPTER 9 PPG (Programmable Pulse Generator)".
●
Waveform generator
• The waveform generator consists of three 16-bit dead timers, three timer control registers, and one 16-
bit waveform control register.
• The waveform generator can generate real-time output, 16-bit PPG waveform output, non-overlap 3-
phase waveform output (for inverter control), and DC chopper waveform output.
• The non-overlap waveform output can be generated on the basis of the dead time of the 16-bit dead
timer (dead time timer function).
• The non-overlap waveform output can be generated when the real-time output is activated in 2 channel
mode (dead time timer function).
• When a real-time output compare match is detected, GATE signal is generated to started or stopped the
PPG timer operation (GATE function).
• When a real-time output compare match is detected, the 16-bit dead timer becomes active. With
generating the GATE signal for controlling the PPG operation, the PPG timer 0 can be start or stop
easily (GATE function).
• DTTI pins can be used to control stopping forcibly.
• DTTI registers can be used to control stopping forcibly.
●
AD activate compare (×3)
• When the 16-bit free-run timer value matches the compare register, A/D can be activated.
• Compare 0 can activate the unit 0 of the A/D converter.
• Compare 1 can activate the unit 1 of the A/D converter.
• Compare 2 can activate the unit 2 of the A/D converter.
