NUM_RXBYTES shows 0xFF on CC1121

Other Parts Discussed in Thread: CC1121

Hello,

Sometimes NUM_RXBYTES shows 0xFF on CC1121.
However, RX FIFO is 128 byte, and I can't understand why the above behavior is occurred.
Could you teach me what condition CC1121 is in when NUM_RXBYTES shows 0xFF?

Best Regards.

In what state are the radio when you read 0xFF and is the value consistent if you read the register multiple times? The RXFIFO will overflow after 128 bytes and then the NUM_RXBYTES will read 0x81.
