4.2 Pin Description
Pin 4(A), 5(B) and 7(Index) are the incremental outputs. The incremental output has a resolution of 10-bit per
pole pair, resulting in a step length of 1.95µm.
Note that Pin 14 (CSn) must be low to enable the incremental outputs.
Pins 12, 13 and 14 are used for serial data transfer. Chip Select (CSn; active low) initiates serial data transfer.
CLK is the clock input and DO is the data output. A logic high at CSn puts the data output pin (DO) to tri-state
and terminates serial data transfer. CSn must be low to enable the incremental outputs. See 6.1.1 for further
options.
