CLRC632
Multiple protocol contactless reader IC (MIFARE/I-CODE1)
Figure 6 shows the microprocessor connection to the CLRC632 using SPI.
Remark: The SPI implementation for CLRC632 conforms to the SPI standard and
ensures that the CLRC632 can only be addressed as a slave.
9.1.4.1
SPI read data
The structure shown in Table 7 must be used to read data using SPI. It is possible to read
up to n-data bytes. The rst byte sent denes both, the mode and the address.
The address byte must meet the following criteria:
the Most Signicant Bit (MSB) of the rst byte sets the mode. To read data from the
CLRC632 the MSB is set to logic 1
bits [6:1] dene the address
the Least Signicant Bit (LSB) should be set to logic 0.
As shown in Table 8, all the bits of the last byte sent are set to logic 0.
