16.1.3 Test signals on pins AUX1 or AUX2
Table 156. Test bus signals: TestBusSel[4:0] = 07h
Table 157. Test bus signals: TestBusSel[4:0] = 0Dh
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
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
pull-down resistor is connected to pin AUX1 or AUX2.
