SCPS253C January 2014 – September 2019 TCA5013
PRODUCTION DATA.
The user card interface in the TCA5013 can be activated in different operating modes. When the START_ASYNC bit (bit [0]; Reg 0x01) is set the user card interface is activated in asynchronous operating mode. When START_SYNC bit (bit[0]; Reg 0x09) is set the user card interface is activated in synchronous type1, synchronous type 2 or manual operating mode. When the START_SYNC bit is set, the operating mode is determined by the ACTIVATION_TYPE bit (bit [6]; Reg 0x09) and CARD_TYPE bit (bit [7] Reg 0x09).
If ACTIVATION_TYPE bit (bit [6]; Reg 0x09) is set to ‘0’, the user card interface is activated in manual operating mode. If the ACTIVATION_TYPE bit is set to’1’, the user card interface is set for automatic activation, where it will be activated in synchronous type 1 or synchronous type 2 operating mode based on CARD_TYPE bit (bit [7] Reg 0x09). If CARD_TYPE bit is set to ‘1’, the card interface is activated in synchronous type 2 operating mode. If CARD_TYPE bit is set to ‘0’ the card interface is activated in synchronous type 1 operating mode.
Any changes made to the START_SYNC, START_ASYNC, CARD_TYPE or ACTIVATION_TYPE bits when the user card interface is active, will be ignored and will have no effect on the device. These new settings will take effect only on the next card interface activation following deactivation (see Deactivation Sequence).
