What is the meaning of T = 1 in T1oI2C ?

T =1 is a peer to peer, half duplex transmission protocol defined in ISO/IEC 7816-3. T=1 protocol usage is very common in the smart card domain.

Please refer to UM11225 for more details.

Is ' T ' means ' Transmission ' and ' 1 ' means the ' 1 ' block of data mentioned in UM11225 ?

Thanks

Yes, you are right.

T=0: asynchronous half duplex character transmission

T=1: asynchronous half duplex block transmission.

Thanks for clarification.
