Multiple protocol contactless reader IC (MIFARE/I-CODE1)
9.14.2 Authentication procedure
The Crypto1 security algorithm enables authentication of MIFARE cards. To obtain valid
authentication, the correct key has to be available in the key buffer of the CLRC632. This
can be ensured as follows:
1. Load the internal key buffer by using the LoadKeyE2 (see Section 11.7.1 on page 97)
or the LoadKey (see Section 11.7.2 on page 97) commands.
2. Start the Authent1 command (see Section 11.7.3 on page 98). When nished, check
the error ags to obtain the command execution status.
3. Start the Authent2 command (see Section 11.7.4 on page 98). When nished, check
the error ags and bit Crypto1On to obtain the command execution status.
10. CLRC632 registers
10.1 Register addressing modes
Three methods can be used to operate the CLRC632:
initiating functions and controlling data by executing commands
conguring the functional operation using a set of conguration bits
monitoring the state of the CLRC632 by reading status ags
The commands, conguration bits and ags are accessed using the microprocessor
interface. The CLRC632 can internally address 64 registers using six address lines.
10.1.1 Page registers
The CLRC632 register set is segmented into eight pages contain eight registers each. A
Page register can always be addressed, irrespective of which page is currently selected.
10.1.2 Dedicated address bus
When using the CLRC632 with the dedicated address bus, the microprocessor denes
three address lines using address pins A0, A1 and A2. This enables addressing within a
page. To switch between registers in different pages a paging mechanism needs to be
used.
Table 36 shows how the register address is assembled.
10.1.3 Multiplexed address bus
The microprocessor may dene all six address lines at once using the CLRC632 with a
multiplexed address bus. In this case either the paging mechanism or linear addressing
can be used.
Table 37 shows how the register address is assembled.
