TRF7962A: TRF7962 FIFO

This is a question of TRF7962A FIFO.

If FIFO errors happened, we know that it is effetive to send a FIFO reset (0x8F).

May we send next commands continouesly after just sending 0x8F, or do we need some delay?

Best regards,

Hello,

a delay after the FIFO reset command is not necessary. You can continue sending commands right after the reset.

Hi! Helfried,

Thank you for your response.

Could you give me some advice again?

When we checked the IRQ register (0Ch), we sometimes received the value, 0xC2 or 0xC0.

Normally you should receive 0X80 (TX comp.) or 0x40 (RX comp.) As a result, we recieved the incorrect UID.

Even in this case, do you mean we may just resend the sequence 0x8F 0x90 0x3D 0x00 0x0F 0x26 (REQA)

without conducting the direct command FIFO reset, 0x8F and dummy 0x00?

Best regards,
