I Notes on timing
Figure 15.3-1 "Timing chart of input/output signals of the µPG timer" shows the output
•
waveform against the input waveform. The duty ratio is fixed at 50%.
• In sync with the first rising pulse after start, the output starts from the 2nd rising pulse.
• Two outputs for one input waveform are only issued using inversion control via the program.
• For the input pulse (waveform at the EXTC pin), use an interval 10 times larger than one
pulse of the internal clock (machine clock).
• To write "11
pins), keep the value at the input pin (EXTC) constant. Otherwise, if a pulse is input to the
input pin (EXTC) when pin output is allowed, the width of the first output pulse may become
shorter than that of the input pulse.
