High-speed differential pulse port and encoder
wiring reference:
When the speed meets the requirements, the low-speed differential pulse
port is preferentially used. When using the high-speed differential pulse
interface, be sure to connect the internal digital ground of the controller to
the high-speed pulse port reference ground of the driver.
