1.
Turn the REQ input ON.
2.
When the OUTR output turns ON, turn the CK input ON.
When the OUTR output turns OFF, save the statuses of OUT0 and OUT1 outputs to the host controller.
3.
Turn the CK input OFF.
Repeat steps 2 and 3 above 28 times.
4.
Turn the REQ input OFF.
The information effective at the time the REQ input turned ON is read.
Turning the REQ input OFF while information is being read will cancel the reading of current position data.
I/O Used for reading current position data
Signal name Description
REQ input This signal turns ON while data is being read.
CK input This signal is used to request data (clock).
OUTR output This signal turns ON when the CK input is OFF and the controller is ready to output
the OUT0 and OUT1 outputs.
This signal turns OFF when the CK input is ON and the controller has completed
outputting the OUT0 and OUT1 outputs.
OUT0 output
OUT1 output These signals represent two data bits. The OUT0 output represents the lower bit,
while the OUT1 output represents the upper bit.
Data is output by 2 bits at a time from the most significant bit every time the CK
input turns ON.
