Contactless reader IC
16.1.3.5
Example: Output test signal RX data stream
Figure 32
shows the data stream that is currently being received. The TestSel2Reg
register’s TestBusSel[4:0] bits are set to 07h to enable test bus signals on pins D1 to D6;
see
Section 16.1.2 “Test bus” on page 80
. The TestSel1Reg register’s TstBusBitSel[2:0]
bits are set 06h (pin D6 = s_data) and AnalogTestReg register is set to FFh (TstBusBit)
which outputs the received data stream on pins AUX1 and AUX2.
(1) RxActive (2 V/div) on pin AUX1.
(2) TxActive (2 V/div) on pin AUX2.
(3) RF field.
