Highly Integrated ISO/IEC 14443 A Reader IC
[1]
This command is the combination of the Transmit and Receive commands.
Transceive
[1]
1Eh
transmits data from FIFO buffer to the card and
automatically activates the receiver after
transmission. The receiver waits until the time defined
in the RxWait register has elapsed before starting.
See
Section 11.2.3 on page 75
.
reads data from the FIFO buffer and writes it to the
EEPROM. See
Section 11.3.1 on page 77
.

ReadE2
03h
reads data from the EEPROM and sends it to the
FIFO buffer. See
Section 11.3.2 on page 79
.
Remark:
Keys cannot be read back
data bytes
LoadKeyE2
0Bh
copies a key from the EEPROM into the key buffer
See
Section 11.6.1 on page 81
.
-
LoadKey
19h
reads a key from the FIFO buffer and loads it into the
key buffer. See
Section 11.6.2 on page 81
.
Remark:
The key has to be prepared in a specific
format (refer to
Section 9.2.3.1 “Key format” on page
13
)
-
Authent1
0Ch
performs the first part of card authentication using the
Crypto1 algorithm. See
Section 11.6.3 on page 82
.
-
Authent2
14h
performs the second part of card authentication using
the Crypto1 algorithm. See
Section 11.6.4 on
page 82
.
reads data from EEPROM and initializes the
MFRC500 registers. See
Section 11.4.1 on page 79
