min and max pulse widths for machine.PWM?

I'm trying to port some Arduino code to micropython that drives a brushless motor using an ESC module. Using an esp8266mod board. The arduino code sets up the pin that writes to ESC like this: #include <Servo.h> ... ESC.attach(9,1000,2000); // (pin, min pulse width, max pulse width in microseconds) ...
