Status Registers
Table 5-22. IRQ Status Register (0Ch)
Displays the cause of IRQ and TX/RX status
Register default is set to 0x00 at POR = H or EN = L, and at each write to the ISO control register. It is also automatically reset at the end
of a read phase. The reset also removes the IRQ flag.
Bit

Function
Comments
B7
Irq_tx
IRQ set due to end of TX
Signals that TX is in progress. The flag is set at the start of TX but the
interrupt request is sent when TX is finished.
B6
Irg_srx
IRQ set due to RX start
Signals that RX SOF was received and RX is in progress. The flag is set at
the start of RX but the interrupt request is sent when RX is finished.
B5
Irq_fifo
Signals the FIFO is 1/3 > FIFO >
Signals FIFO high or low (less than 4 or more than 8)
2/3
B4
Irq_err1
CRC error
Indicates receive CRC error
B3
Irq_err2
Parity error
Indicates parity error
B2
Irq_err3
Byte framing or EOF error
Indicates framing error
B1
Irq_col
Collision error
For ISO14443A and ISO15693 single sub-carrier
B0
Irq_noresp
No-response interrupt
Signal to MCU that next slot command can be sent
Table 5-23. Collision Position and Interrupt Mask Register (0Dh)
Register default is set to 3E at POR = H and EN = L. Collision bits reset automatically after read operation.
