Game Port Legacy Status Register (GMPLST)
This register is functional in all Game Port operation modes. Reading this register returns the status and the state of Device
A and B button and Axis pins, as defined in the table below. Writing to the offset of this register initiates a game device po-
sition reading process by forcing a low pulse to be driven on the axis pins in Legacy and Enhanced modes, and by initializing
all position counters in Enhanced mode.
