Please suggest</P></BODY></HTML> Wed, 12 Oct 2016 08:49:56 GMT shivakeerthan_b 2016-10-12T08:49:56Z Why clock is not received during asynchronous communication in TDA8035 chip? https://community.nxp.com/t5/NFC/Why-clock-is-not-received-during-asynchronous-communication-in/m-p/629279#M1286 <HTML><HEAD></HEAD><BODY><P>I am using TDA8035 chip as interface between smart card reader and micro controller.
