■ 16-bit Input Capture (× 4)
Input capture consists of 4 independent external input pins, the corresponding capture register and capture
control register. By detecting any edge of the input signal from the external pin, the value of the 16-bit free-
run timer can be stored in the capture register and an interrupt is generated simultaneously.
• 3 types of trigger edge (rising edge, falling edge and both edge) of the external input signal can be
selected and there is indication bit to show the trigger edge is rising or falling.
• 4 input captures can be operated independently.
• An interrupt is generated by detecting a valid edge from external input.
• Channel 0 and 1 share interrupt #33.
• Channel 2 and 3 share interrupt #35.
■ 16-bit PPG Timer (× 1)
The 16-bit PPG timer 0 is used to provide a PPG signal for waveform generator. The detail of 16-bit PPG
timer 0 is described in Chapter 13.
■ Waveform Generator
The waveform generator consists of three 16-bit timer registers, three timer control registers and 16-bit
waveform control register.
With waveform generator, it is possible to generate real-time output, 16-bit PPG waveform output, non-
overlap 3-phase waveform output for inverter control and DC chopper waveform output.
• It is possible to generate a non-overlap waveform output based on dead-time of 16-bit timer. (Dead-time
timer function)
• It is possible to generate a non-overlap waveform output when real-time output is operated in 2-channel
mode. (Dead-time timer function)
• By detecting real-time output compare match, GATE signal of the PPG timer operation will be
generated to start or stop PPG timer operation. (GATE function)
• When a match is detected by real-time output compare, the 16-bit timer is activated. The PPG timer can
be started or stopped easily by generating a GATE signal for PPG operation until the 16-bit timer stops.
(GATE function)
• Forced stop control using DTTI0 pin input
