This is a breaking change, making the hardware PWM on the nrf port compatible with the other ports providing machine.PWM. Frequency range 4Hz - ~5.4 MHz. The base clock range is 125kHz to 16 MHz, and the divider range is 3 - 32767. The hardware supports up to four outputs per PWM device with different duty cycles, but only one output is (and was) supported.
