Quadrature Mode Timing
The output waveforms emulate the output from encod-
ers. With the resolution set to 400 cpi, from one to five
quadrature states can exist within one frame time. The
minimum state time is 133 µs. If the resolution is 800 cpi,
then up to ten quadrature states can exist within a frame
time. If the motion within a frame is greater than these
values, the extra motion will be reported in the next frame.

The following diagrams (see Figures 15, 16 and 17) show
the timing for positive X motion, to the right, or positive Y
motion, up. If a power down via the PD pin occurs during
a transfer, the transfer will resume after PD is de-asserted.
The timing for that quadrature state will be increased by
the length of the PD time.
