PULSE OUTPUT PORT MODE
9.4 Pulse output port mode operation
9.4.3 Operation at external trigger
➀ Each time when a valid edge of a signal input to pin RTPTRG0 (Note) is input, the contents of the pulse
output data bits of three-phase output data register 0 are output from the corresponding pulse output
pins. When the pulse width modulation is selected, the pulse width modulation is applied to “H” level
output.
➀ The INT interrupt request bit is set to “1” when a valid edge (➀) is input. (Refer to section “9.4.1 Pulse
3
output trigger.”) The interrupt request bit retains “1” until the interrupt request is accepted or it is
cleared by software.
➀ Write the next output data into three-phase output data register 0 during an INT
after the confirmation of an INT interrupt request occurrence).
