I find spec only 0/1,so how should I know state of GPIO(High/Low、OD/PP)?
First,the device does not support open drain on all the pins. Only pins that are configured for a protocol that requires open-drain (e.g;, LPI2C, LPUART single-wire) will work in open-drain mode.
Regarding the PP,you can take a look at the Pin Control Register(PORT_PCRn) ,
BR!
Jim,
Thacks a lot~
The PE/PS show internal,I want to know if my output is correct,are there any other registers?
Dose DSE represent low or high output voltage no matter OD or PP?
I haven't seen such a register, and I haven't seen such a function in the driver library. I think this should not be possible.
BR!
Jim,
Thanks a lot~
