(4) Timing of holding data by capture register
(5) Setting valid edge
(6) Re-triggering one-shot pulse
(a) When the valid edge is input to the TI000/TI010 pin and the reverse phase of the TI000 pin is detected while
(b) The values of CR000 and CR010 are not guaranteed after 16-bit timer/event counter 00 stops.
Set the valid edge of the TI000 pin while the timer operation is stopped (TMC003 and TMC002 = 00). Set the
valid edge by using ES000 and ES001.
Make sure that the trigger is not generated while an active level is being output in the one-shot pulse output mode.
Be sure to input the next trigger after the current active level is output.
CR000/CR010 is read, CR010 performs a capture operation but the read value of CR000/CR010 is not
guaranteed. At this time, an interrupt signal (INTTM000/INTTM010) is generated when the valid edge of the
TI000/TI010 pin is detected (the interrupt signal is not generated when the reverse-phase edge of the TI000
pin is detected).
When the count value is captured because the valid edge of the TI000/TI010 pin was detected, read the
value of CR000/CR010 after INTTM000/INTTM010 is generated.
