Bits 31:24 – TXAEE[7:0] Transmit Abort External Error

This bit field counts the number of frames that were aborted and dropped due to an external SPI host error. Such errors include:
  • Repeated Frame Start - the device received two start-of-frame indication from the SPI host without an end-of-frame.
  • Frame received from the SPI host exceeds 1536 bytes in length
  • Transmit Frame Check Sequence Error - The SPI host appended Frame Check Sequence (FCS) does not match the frame data received from the host. This may indicate a bit error on SPI, or the host incorrectly calculated the FCS.

This field will saturate at 0xFF and will be cleared on read.

Bits 23:16 – TXFUR[7:0] Transmit FIFO Underruns

This bit field counts the number of frames that were dropped due to transmit FIFO underrun during the middle of frame transmission.

This field will saturate at 0xFF and will be cleared on read.

Bits 15:8 – TXBUR[7:0] Transmit Buffer Underruns

This bit field counts the number of frames that were dropped due to buffer underrun during the middle of frame transmission.

This field will saturate at 0xFF and will be cleared on read.
