(2) Measurement of two pulse widths with free-running counter
Figure 6-25. Control Register Settings for Measurement of Two Pulse Widths with Free-Running Counter
Remark 0/1: Setting 0 or 1 allows another function to be used simultaneously with pulse width measurement.
When 16-bit timer counter 00 (TM00) is operated in free-running mode, it is possible to simultaneously measure
the pulse widths of the two signals input to the TI000 pin and the TI010 pin.
When the edge specified by bits 4 and 5 (ES000 and ES001) of prescaler mode register 00 (PRM00) is input to
the TI000 pin, the value of TM00 is taken into 16-bit timer capture/compare register 010 (CR010) and an interrupt
request signal (INTTM010) is set.
Also, when the edge specified by bits 6 and 7 (ES100 and ES101) of PRM00 is input to the TI010 pin, the value
of TM00 is taken into 16-bit timer capture/compare register 000 (CR000) and an interrupt request signal
(INTTM000) is set.
Specify both the rising and falling edges as the edges of the TI000 and TI010 pins, by using bits 4 and 5 (ES000
and ES001) and bits 6 and 7 (ES100 and ES101) of PRM00.
Sampling is performed using the count clock cycle selected by prescaler mode register 00 (PRM00), and a
capture operation is only performed when a valid level of the TI000 or TI010 pin is detected twice, thus
eliminating noise with a short pulse width.
