With its low power consumption and small package options, the Cypress MoBL-USB™ TX2UL transceiver offers an ideal design for mobile applications. The TX2UL provides configuration and control registers that comply with the UTMI+ Low Pin Interface (ULPI) Specification, Revision 1.1. This application note describes how to configure these registers.


TX2UL supports the immediate register set. It provides 11 control and configuration registers that allow the processor to access the ULPI bus with ULPI protocol.
