Introduction

MagTek Qwantum ASIC supports two distinct operating modes: Data Strobe mode and SPI mode. This document describes Qwantum ASIC operating in SPI mode and provides guidance for firmware implementation. It contains a description of the SPI requirements, the ASIC features, the reference firmware functions and the ASIC registers.
