8.4.5 User Card Insertion / Removal Detection

User card interface module in the TCA5013 has a PRES pin that is used to detect the presence of a card in that interface. In normal application the signal is connected to a switch that opens or closes when a card is inserted. Whenever a transition is seen on the PRES pin, the PRESL bit (Reg 0x00, bit 2) will be set and INT pin is asserted. Because this transition is associated with a mechanical switch, there is an internal debounce of ~20 ms before the PRESL bit is set and the INT is asserted. If the device sees a transition on the PRESL pin when the card interface is active, the device initiates a card deactivation sequence (see Deactivation Sequence). TCA5013 is capable of detecting card insertion even when it is in shutdown mode (see Shutdown Mode).

In addition to the PRESL_UC bit mentioned above, there is also a PRES_UC bit (Reg 0x00, bit 2), which indicates to the host whether or not a card is present in the user card slot. In order to accommodate different card cage topologies, the TCA5013 can be configured to detect card presence with a low to high or high to low, transition on the PRES pin. The CARD_DETECT_UC bit (Reg 0x01, bit 2) is used to configure the device for different card detection topologies. If CARD_DETECT_UC = 0 indicates to the TCA5013 that when a card is inserted in the slot, the PRES pin shall be low. CARD_DETECT_UC = 1 indicates to the host that when a card is inserted in the slot the PRES pin shall be high. The status of the PRES_UC bit is based on the status of the PRES pin and the CARD_DETECT_UC bit. The truth table in Table 1 shows the PRES_UC bit status based on the CARD_DETECT_UC bit and the PRES pin. When coming out of power off mode (see Power Off Mode) or shutdown mode (see Shutdown Mode) the CARD_DETECT_UC = 0. If there is a state transition on the PRES pin when the device is in shutdown mode, the INT pin asserted (after the 20 ms debounce).

Figure 9 to Figure 14 show timing waveforms of device power up and coming out of shutdown with and without a card inserted in the system. In below figures’ low to high PRES topology’ means that a high level on the PRES pin indicates a card is present. In below figures high to low PRES topology’ means that a low level on the PRES pin indicates a card is present. The below figures also show operation of INT pin and interrupt status register. For detailed description of the interrupt operation, refer to Interrupt Operation section.
