TDA8007BHL

Multiprotocol IC card interface

8.2.1 General registers

8.2.1.1 Card select register

The Card Select Register (CSR) is used for selecting the card on which the UART will act,

and also to reset the ISO UART.

[1] Register value at reset: all significant bits are cleared after reset, except bits CS7 to CS4 which are set to

their default value

[1] Bits SC1, SC2 and SC3 must be set at one at a time. After reset no card is selected by default

8.2.1.2 Hardware status register

The Hardware Status Register (HSR) gives the status of the chip after a hardware

problem has been detected.

[1] Register value at reset: all significant bits are cleared after reset, except bit SUPL which is set within

pulse RSTOUT.

Bit Symbol Description

7CS7 IC identifier: default value for identification the IC

0010 = TDA8007BHL/C2

0011 = TDA8007BHL/C3 or TDA8007BHL/C4

3RIU

reset ISO UART: When reset, this bit resets a large part of the UART

registers to their initial value. Bit RIU must be reset before any

activation; logic 0 for at least 10 ns duration. Bit RIU must be set to

logic 1 by software before any action on the UART can take place.

2SC3 select card 3: If bit SC3 = 1, then card 3 is selected.

1SC2 select card 2: If bit SC2 = 1, then card 2 is selected.

0SC1 select card 1: If bit SC1 = 1, then card 1 is selected.
