16. Test information
16.1 Test signals
16.1.1
Self test
The MFRC522 has the capability to perform a digital self test. The self test is started by
using the following procedure:
1. Perform a soft reset.
2. Clear the internal buffer by writing 25 bytes of 00h and implement the Config
command.
3. Enable the self test by writing 09h to the AutoTestReg register.
4. Write 00h to the FIFO buffer.
5. Start the self test with the CalcCRC command.
6. The self test is initiated.
7. When the self test has completed, the FIFO buffer contains the following 64 bytes:
FIFO buffer byte values for version 92h:
0x00, 0xEB, 0x66, 0xBA, 0x57, 0xBF, 0x23, 0x95, 0xD0, 0xE3, 0x0D, 0x3D, 0x27, 0x89,
0x5C, 0xDE, 0x9D, 0x3B, 0xA7, 0x00, 0x21, 0x5B, 0x89, 0x82, 0x51, 0x3A, 0xEB, 0x02,
0x0C, 0xA5, 0x00, 0x49, 0x7C, 0x84, 0x4D, 0xB3, 0xCC, 0xD2, 0x1B, 0x81, 0x5D, 0x48,
0x76, 0xD5, 0x71, 0x61, 0x21, 0xA9, 0x86, 0x96, 0x83, 0x38, 0xCF, 0x9D, 0x5B, 0x6D,
0xDC, 0x15, 0xBA, 0x3E, 0x7D, 0x95, 0x3B, 0x2F
16.1.2
Test bus
The test bus is used for production tests. The following configuration can be used to
improve the design of a system using the MFRC522. The test bus allows internal signals
to be routed to the digital interface. The test bus comprises two sets of test signals which
are selected using their subaddress specified in the TestSel2Reg register’s
TestBusSel[4:0] bits. The test signals and their related digital output pins are described in
Table 156
and
Table 157
.
