Are the PWM pins a hardware feature or software kernel feature?

I've looked through the datasheet of the EX and can only find one mention of PWM. I'm using an 86 ONE without Arduino libs and so the question comes--Is the 32-bit 11-pin PWM lines something generated by the OS? If it's hardware registers that reside natively on the SoC, where in the datasheet is that discussed?

Hi, jejump,

The PWM on 86Duino is Hardware function, if want to use PWM under DOS, there is a example(including source code)here:
In example, only PWM code(no GPIO, no IRQ), run it under DOS on 86Duino, we will get 30% duty on GPIO port2 pin1(same as ~9), if want to get pin mapping betrween GPIO and PWM, see this file:
About the operation of PWM registers, in example, we can refer mcm.cpp/io.cpp. hope to help you.
