PRODUCTION DATA.
The RST pin operation depends on the mode in which the card interface has been activated. For user card interface and all the SAM card interfaces, in asynchronous mode (see Asynchronous Operating Mode) the RST pin status is automatically controlled by the TCA5013 internal state machine.
In synchronous mode (Synchronous Type 1 Operating Mode and Synchronous Type 2 Operating Mode) the RST pin status is controlled by the TCA5013 internal state machine, until the activation sequence is complete. After activation is complete, the RST pin status is controlled by RST bit (bit [3]) in the user card synchronous mode settings register (Reg 0x09). This operation is described in further detail in Synchronous Type 1 Operating Mode and Synchronous Type 2 Operating Mode.
