Test signals on pins AUX1 or AUX2
The MFRC522 allows the user to select internal signals for measurement on pins AUX1 or
AUX2. These measurements can be helpful during the design-in phase to optimize the
design or used for test purposes.
Table 158
shows the signals that can be switched to pin AUX1 or AUX2 by setting
AnalogSelAux1[3:0] or AnalogSelAux2[3:0] in the AnalogTestReg register.
Remark:
The DAC has a current output, therefore it is recommended that a 1 k
Ω
pull-down resistor is connected to pin AUX1 or AUX2.

Example: Output test signals TestDAC1 and TestDAC2
The AnalogTestReg register is set to 11h. The output on pin AUX1 has the test signal
TestDAC1 and the output on pin AUX2 has the test signal TestDAC2. The signal values of
TestDAC1 and TestDAC2 are controlled by the TestDAC1Reg and TestDAC2Reg
registers.
