Using the AEAS-7000
IMPORTANT NOTE:
The RC-filter combination, especially on VDDA, is used
to filter spikes and transients and is strongly
recommended. It is advised that the tantalum caps be
put as close to the VDD and VDDA pins as possible.
It is recommended to ground the PROBE_ON pin during
normal operation.
Leave PCL unconnected.
A09N and A0N are the negative cosine and sine waves,
the negative versions of A09P and A0P.
D0 is used to check the D0 signal. D0 is the digitized
signal of A0. DPROBE is used to check D09, the digitized
signal of A09. Recommended to be used for testing
purpose only.

KORR is for Gray Code correction for 12 bits resolution
only.
MSBINV is for user to change between counting up and
counting down for a given rotating direction. MSB(D11)
will always be sent out to DOUT first.
LEDR, do not connect to this pin.
LERR will be high when the light output perceived by
the photo diode array is low, and the LED current is
under overdrive mode. This is an indicator when light
intensity is at a critical stage affecting the performance
of the encoder.
It is caused by contamination of the codewheel or LED
degradation.
