8.2.1
8.2.1.1
The Card Select Register (CSR) is used for selecting the card on which the UART will act, and also to reset the
ISO UART.
Table 1 Register CSR (address 00H; write and read); note 1
Note
1. Register value at reset: all significant bits are cleared after reset, except bits CS7 to CS4 which are set to their default
Table 2 Description of CSR bits; note 1
Note
1. Bits SC1, SC2 and SC3 must be set one at a time. After reset, no card is selected by default.
8.2.1.2
The Hardware Status Register (HSR) gives the status of the chip after a hardware problem has been detected.
Table 3 Register HSR (address 0FH; read only); note 1
Note
1. Register value at reset: all significant bits are cleared after reset, except bit SUPL which is set within pulse RSTOUT.

IC identification. Default value for identifying the IC:
0010 = TDA8007BHL/C2
0011 = TDA8007BHL/C3
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.
Select Card 3. If bit SC3 = 1, then card 3 is selected.
Select Card 2. If bit SC2 = 1, then card 2 is selected.
Select Card 1. If bit SC1 = 1, then card 1 is selected.
