Read Register
The READ_REG register contains the data read from the
interface and from the external card. The selected register is
transferred to the MISO pin during the MOSI sequence
(CS = Low). Table 3 gives the bits definition.
Depending upon the programmed SPI_MODE, the
content of READ_REG is transferred on the MISO line
READ_REG
either on the Positive going (SPI_MODE = Special) or upon
the Negative going slope (SPI_MODE = Normal) of the
CLK_SPI signal. The external microcontroller shall discard
the three high bytes since they carry no valid data.

ASYNCHRONOUS MODE
In this mode, the CRD_C4 and CRD_C8 pins are used to
define the physical addresses of the interfaces when a bank
of up to four NCN6001 share the same digital bus.
SYNCHRONOUS MODE
In this mode, CRD_C4 and CRD_C8 are connected to the
smart card and it is no longer possible to share the CS signal
with other device. Consequently, a dedicated Chip Select
signal must be provided when the interfaces operate in a
multiple operation mode (Figure 33).
On the other hand, since bits [b4 – b0] of the MOSI
register contain the smart card data, programming the
CRD_VCC output voltage shall be done by sending a
previous MOSI message according to Table 1 and Table 2.
The CRD_RST pin reflects the content of the MOSI
WRT_REG[b4] during the chip programming sequence.
Since this bit shall be Low to address the internal register of
the chip, care must be observed as this signal will be
immediately transferred to the CRD_RST pin.
Since no physical address can exist when the chip operates
in this mode, the MOSI register must use the format
%100XXXXX to program the chip (%100 prefix, XXXXX
data).
