1.7 Zensys Z-WAVE devices - SPI connections

1.7.1 Overview

The Zensys 100 / 200 / 300 series Z-WAVE devices use a standard 'SPI interface' for In-System
Programming – see diagram below. A connection to the RESET_N pin is also required to force the
device into programming mode. The diagram below shows the connections required between the
programmer and the Target IC in order to program these devices.
