Contactless reader IC
16.1.3.3
Example: Output test signals ADC I-channel and ADC Q-channel
Figure 30
shows the channel behavior test signals ADC_I and ADC_Q on pins AUX1 and
AUX2, respectively. The AnalogTestReg register is set to 56h.
16.1.3.4
Example: Output test signals RxActive and TxActive
Figure 31
shows the RxActive and TxActive test signals relating to RF communication.
The AnalogTestReg register is set to CDh.
At 106 kBd, RxActive is HIGH during data bits, parity and CRC reception. Start bits
are not included
At 106 kBd, TxActive is HIGH during start bits, data bits, parity and CRC transmission
At 212 kBd, 424 kBd and 848 kBd, RxActive is HIGH during data bits and CRC
reception. Start bits are not included
At 212 kBd, 424 kBd and 848 kBd, TxActive is HIGH during data bits and CRC
transmission
(1) ADC_I (1 V/div) on pin AUX1.
(2) ADC_Q (500 mV/div) on pin AUX2.
(3) RF field.
