This document is intended as an introduction and reference for using Special Direct Mode and Direct Mode 1 with the TRF79xxA devices. Previously, Direct Mode 0 was required when using the TRF79xxA with popular non-ISO standard RFID protocols, such as MIFAREĀ® Classic. Special Direct Mode and Direct Mode 1 reduce the overall system complexity and cost in these types of application use cases. In summary, these modes can be used to simplify the implementation of proprietary RFID protocols with low-cost microcontrollers which might have intentional resource limitations, such as the MSP430G2xx series devices.
