Notes:

1. GND_C is mode selection line used at

startup to determine encoder mode:

VCC/Floating: SPI Communication Mode

Ground: Normal Operation Mode

Standard use requires attaching GND_C

Pin# 14 to GND in order to get Commutation output.

SPI Communication mode allows the user to write

parameters to the encoder via SPI link, contact CUI

Inc. for more details.
