20.1 Selftest
20.2 Testbus
The PN512 has the capability to perform a digital selftest. To start the selftest the following
procedure has to be performed:
The testbus is implemented for production test purposes. The following configuration can
be used to improve the design of a system using the PN512. The testbus allows to route
internal signals to the digital interface. The testbus signals are selected by accessing
TestBusSel in register TestSel2Reg.

1. Perform a soft reset.
2. Clear the internal buffer by writing 25 bytes of 00h and perform the Config Command.
3. Enable the Selftest by writing the value 09h to the register AutoTestReg.
4. Write 00h to the FIFO.
5. Start the Selftest with the CalcCRC Command.
6. The Selftest will be performed.
7. When the Selftest is finished, the FIFO contains the following bytes:
