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 29
.

The TxControl register ModulatorSource[1:0] bits define the signal used to modulate the
transmitted 13.56 MHz energy carrier. The modulated signal drives pins TX1 and TX2.
