Meaning of underscored pins on ChipKit uC32

[Digisol]

Hello there!
I am a newbie using ChipKit uC32, and wonder what is the meaning of underscored pins on J5 and J6. Pins 3, 5,6,9,10
May I use all J5 and J6 pins as I/O?

Thanks in advance for any help.

The underscore means that it is an "analog output" pin. This is done via a PWM operation. So those pins can be used to run the analogWrite functions.

Hi @Digisol,

I believe you can use all of the pins on j5 and j6 as digital I/O. Some of the I/O pins on J5 and J6 are also used for I2C and output compares and .... I would look at the pinout tables 3.70-3.7.2 here(reference manual) for more information. Here is the resource page for the uC32 as well.

cheers,

Jon

Thank you for the quick response! I failed to find it on reference manual, resource page and Internet.
