CLRC632
Standard multi-protocol reader solution
Remark: Pin MFIN can only be accessed at 106 kBd based on ISO/IEC 14443 A. The
Manchester signal and the Manchester signal with subcarrier can only be accessed on pin
MFOUT at 106 kBd based on ISO/IEC 14443 A.
9.11.1 Serial signal switch block diagram
Figure 14 shows the serial signal switches. Three different switches are implemented in
the serial signal switch enabling the CLRC632 to be used in different configurations.
The serial signal switch can also be used to check the transmitted and received data
during the design-in phase or for test purposes. Section 15.2.1 on page 110 describes the
analog test signals and measurements at the serial signal switch.
Remark: The SLR400 uses pin name SIGOUT for pin MFOUT. The CLRC632
functionality includes the test modes for the SLRC400 using pin MFOUT.

Section 9.11.2, Section 9.11.2.1 and Section 9.11.2.2 describe the relevant registers and
settings used to configure and control the serial signal switch.
9.11.2 Serial signal switch registers
The RxControl2 register DecoderSource[1:0] bits define the input signal for the internal
Manchester decoder and are described in Table 30.
