7.Q & A
7.8 How do I invert the output polarity?
Output polarity specification
The polarity in the normal state can be specified as follows:
Use the PPG Output Polarity Specification bit (PCN.OSEL) to set.
(“Normal state” means the state in which pulse output is not executed.)
(See “8. Caution (Page No.821)”.)
7.9 How do I program a pin as a PPG output pin?
-> PPG pin output setting
Software programming allows ports to be switched to PPG pin output.
Output Level in Normal State PPG Output Polarity Specification Bit (OSEL)
To enable “L” level output (normal polarity)
Set “0”.
To enable “H” level output (inverted polarity)
Set “1”.
