TRF7970A: IRQ Status Register (0x0C) - BIT2 always set

Hi all,

I'm trying to impement simple NFC reader and have purshaised EVM.

BIT2 in IRQ status register is always set, even right after SOFT_INIT command (reads as 0x04). When I transmit REQA, IRQ is 0x84; 8 is OK, but 4?

Even more, it does not reset to 0x00 after reading: sequental read of the register after reset results in 0x04, 0x04.

Any suggestions?

Thanks in advance.
