Description
Current position value.
Description
Current maximum position value.
Description
Position compare value 0.
Description
Position compare value 1.
This register contains the current value of the encoder position. Increments or decrements
when encoder counts occur, depending on the direction of rotation.
This register contains the maximum value of the encoder position. In forward rotation the
position register resets to zero when the position register exceeds this value. In reverse
rotation the position register resets to this value when the position register decrements
from zero.
This register contains a position compare value. This value is compared against the
current value of the position register. Interrupts can be enabled to interrupt when the
compare value is equal to the current value of the position register.
This register contains a position compare value. This value is compared against the
