Sample Setup Procedure for One-Shot pulse Output: An example of the setup procedure for
one-shot pulse output is shown in figure 10.48.
1. Set the first-stage counter clock ' in prescaler register 1 (PSCR1), and select the second-stage
2. Set the port C control register (PCCR) corresponding to the waveform output port to ATU one-
3. Set the one-shot pulse width in the down-counter (DCNT) corresponding to the port set in (2).
4. Set the corresponding bit (DST10A to DST10H) to 1 in the down-count start register (DSTR)
counter clock " with the CKSEL bit in timer control register TCR10.
shot pulse output. Also set the corresponding bit to 1 in the port C IO register (PCIOR) to
specify the output attribute.
If necessary, an interrupt request can be sent to the CPU when the down-counter underflows by
making the appropriate setting in the interrupt enable register (TIERF).
