Description of Control Words 0 and 1

Bit Description

00…02 02 01 00 Mode Selection Bits

0 0 0 Counting on positive (rising) edge of input signal A. (Up/dwn

counting determined by B.)

0 0 1 Quadrature encoder X1

0 1 0 Quadrature encoder X2

0 1 1 Quadrature encoder X4

1 0 0 Counting up on positive edge of input signal A, and counting

down on positive edge of input signal B.

1 0 1 No count function

03 Preset (Reset) bit - A positive edge on this bit moves the value in Preset X to

Counter X, independent of Preset Enable. Note: To use Preset as a Reset, use a count

value of 0000 in the Preset Value word.

04 Enable Z Preset (Reset) bit - When this bit is set (1), a positive edge on Z preloads

Counter X = Preset X, independent of Cal Enable. Note: If Z is configured to do Store

and Preset (Reset), the Store will occur first.

05 Count Enable bit - When this bit is set (1), the pulse counter is enabled.

Calibration Control Bits 06-08

06 Enable bit - When this bit is set (1), the pulse counter can be calibrated.

07 Direction bit - When this bit is set (1), calibration is performed in a negative

direction; when reset (0), calibration is performed in a positive direction.

08 Reset bit - Calibration is acknowledged and a new calibration is enabled on a

positive edge on this bit.
