CAM state register
USINT
R
The CAM-state-register serves
for the representation of the cam
switching states in dependence
on the position of the encoder
shaft. For this purpose, the value
of the register must be broken
down in binary notation (see
below). Each bit of the octet
shows the status of a certain
switching position.
See 4.4.2.1

CAM
enable
register
USINT
RW
Each cam switch position of the
CAM channel in the encoder
must
be
"switched
on"
individually
for
use.
The
"switching on" of the individual
CAM works by writing the
appropriate
value
into
the
attribute. The correct value can
be found by setting the bit to 1 in
binary notation for each cam
switch position that is to be
active.
See 4.4.2.2

CAM
polarity
register
USINT
RW
The CAM Polarity register can
be used to change the polarities
of each cam switch position in
the CAM channel. By default, the
polarity is set so that all cam
positions "jump" to High (= 1b) at
position values in their limits. By
changing the individual bits, the
