Near Field Communication (NFC) controller
• NFCIP-1 106 kbps passive communication mode:
The MIFARE anticollision is finished and the command changes automatically to
Transceive. The FIFO contains the ATR_REQ frame including the start byte F0h. The
bit TargetActivated in the register CIU_Status2 is set to logic 1
• NFCIP-1 212 and 424 kbps passive communication mode:
The FeliCa polling command is finished and the command has automatically changed
to Transceive. The FIFO contains the ATR_REQ frame. The bit TargetActivated in the
register CIU_Status2 is set to logic 1.
• NFCIP-1 106, 212 and 424 kbps active communication mode:
This command is changing automatically to Transceive. The FIFO contains the
ATR_REQ frame. The bit TargetActivated in the register CIU_Status2 is set to logic 0.
For 106 kbps only, the first byte in the FIFO indicates the start byte F0h and the CRC
is added into the FIFO.
• ISO/IEC 14443A/MIFARE (Card Operating mode):
The MIFARE anticollision is finished and the command has automatically changed to
Transceive. The FIFO contains the first command after the Select. The bit
TargetActivated in the register CIU_Status2 is set to logic 1.
• FeliCa (Card Operating mode):
The FeliCa polling command is finished and the command has automatically changed
to Transceive. The FIFO contains the command after the Polling in the FeliCa
protocol. The bit TargetActivated in the register CIU_Status2 is set to logic 1.
