DS8007A Maxim, DS8007A Datasheet - Page 15

• Manufacturer Part Number: DS8007A
• Description: The DS8007A multiprotocol dual smart card interface is an automotive grade, low-cost, dual smart card reader interface supporting all ISO 7816, EMV™, and GSM11-11 requirements
• Manufacturer: Maxim

Special control registers that the host computer/micro-
controller accesses through the parallel bus manage
most DS8007A features. Many of the registers,
although only mentioned once in the listing, are dupli-
cated for each card interface. The PDR, GTR, UCR1,
UCR2, and CCR registers exist separately for each of
the three card interfaces. The PCR register is provided
only for card interface A and card interface B.
The specific register to be accessed is controlled by
the current setting of the SC3–SC1 bits in the Card
Select Register. For example, there are three instances
of the UART Control Register 1 (UCR1) at address 06h.

* u = unchanged, x = always reflects state of external device pin, even when RIU = 0.
Note: Writes to unimplemented bits have no effect. Reads of unimplemented bits return 0.

If the SC3–SC1 bits are configured so that card A is
selected, then all reads and writes to address 06h only
affect card A. If SC3–SC1 are changed to select card
B, then all reads and writes to address 06h only affect
card B, etc.
In addition, some registers have different functions
based on whether the register is being read from or writ-
ten to. An example of this are the UART Receive
(URR)/UART Transmit (UTR) registers located at address
0Dh. Although they share the same address, during read
operations the receive register is read, and write opera-
tions go to a separate transmit register. This selection
requires no extra configuration by the software.
