Resolution Control Capabilities
The CYONS1001x sensors support a variety of resolution
control modes that offer users both precision tracking and flexi-
bility. The resolution control capabilities of each sensor are
summarized in Table 8. The various resolution control modes are
described in the following sections.
Standard Resolution Control
In standard control mode, resolution is adjusted in increments of
200 or 400 cpi, depending on the sensor.
X/Y Resolution Control
In x/y resolution control mode, the x-direction and y-direction
resolution are independent: they need not be set to the same
value. Resolution in either direction is adjusted in increments of
50 cpi.
Fine Resolution Control
Fine control mode enables continuously variable resolution in
increments of less than 1 cpi.
Setting Sensor Resolution
Sensor resolution is controlled by the change resolution
command described on page 11.
■ Standard resolution control requires a single change resolution
command to change the resolution in both the x and y direction.
■ X/Y resolution control requires a separate change resolution
command for each direction.
■ Fine resolution control requires two change resolution
commands to specify the resolution. In both commands, the
two most significant bits select the resolution control mode. In
the first command, bits 5-0 provide the first half of the resolution
code. In the second command, bits 5-0 provide the second half
of the resolution code.
