8.2 Control registers
The TDA8007BHL/C has two complete analog interfaces
which can drive cards 1 and 2. The data to and from these
two cards shares the same ISO UART. The data to and
from a third card (card 3), externally interfaced (with a
TDA8020 or TDA8004 for example), may also share the
same ISO UART.
Cards 1, 2 and 3 have dedicated registers for setting the
parameters of the ISO UART (see Fig.8):
• Programmable Divider Register (PDR)
• Guard Time Register (GTR)
• UART Configuration Register 1 (UCR1)
• UART Configuration Register 2 (UCR2)
• Clock Configuration Register (CCR).
Cards 1 and 2 also have dedicated registers for controlling
their power and clock configuration. The Power Control
Register (PCR) for card 3 is controlled externally.
Register PCR is also used for writing or reading on the
auxiliary card contacts C4 and C8.
Card 1, 2 or 3 can be selected via the Card Select
Register (CSR). When one card is selected, the
corresponding parameters are used by the ISO UART.
Register CSR also contains one bit for resetting the
ISO UART (bit RIU = 0). This bit is reset after power-on
and must be set to logic 1 before starting with any one of
the cards. It may be reset by software when necessary.
When the specific parameters of the cards have been
programmed, the UART may be used with the following
registers:
• UART Receive Register (URR)
• UART Transmit Register (UTR)
• UART Status Register (USR)
• Mixed Status Register (MSR).
In reception mode, a FIFO of 1 to 8 characters may be
used and is configured with the FIFO Control Register
(FCR). This register is also used for the automatic
re-transmission of Not AcKnowledged (NAK) characters in
transmission mode.
The Hardware Status Register (HSR) gives the status of
the supply voltage, of the hardware protections and of the
card movements.
Registers HSR and USR give interrupts on pin INT when
some of their bits have been changed.
Register MSR does not give interrupts and may be used in
the polling mode for some operations; for this use, some of
the interrupt sources within the registers USR and HSR
may be masked.
A 24-bit time-out counter may be started to give an
interrupt after a number of ETU programmed into the
Time-Out Registers TOR1, TOR2 and TOR3. This will
help the microcontroller in processing different real-time
tasks (ATR, WWT, BWT, etc.). This counter is configured
with a Time-Out counter Configuration (TOC) register. It
may be used as a 24-bit counter or as a 16-bit plus 8-bit
counter. Each counter can be set to start counting once
data has been written, or on detection of a START bit on
the I/O, or as auto-reload.
