Name:
Access Type:
• DONE: Management Done
The PHY maintenance register has completed its operation. Cleared on read.
• RCOM: Receive Complete
A frame has been stored in memory. Cleared on read.
• RBNA: Receive Buffer Not Available
Cleared on read.
• TOVR: Transmit Buffer Overrun
Software has written to the Transmit Address Register (ETH_TAR) or Transmit Control Register (ETH_TCR) when BNQ of
the Transmit Status Register (ETH_TSR) was not set. Cleared on read.
• TUND: Transmit Buffer Underrun
Ethernet transmit buffer underrun. The transmit DMA did not complete fetch frame data in time for it to be transmitted.
Cleared on read.
• RTRY: Retry Limit
Retry limit exceeded. Cleared on read.
• TBRE: Transmit Buffer Register Empty
Software may write a new buffer address and length to the transmit DMA controller. Cleared by having one frame ready to
transmit and another in the process of being transmitted. Cleared on read.
• TCOM: Transmit Complete
Set when a frame has been transmitted. Cleared on read.
• TIDLE: Transmit Idle
Set when all frames have been transmitted. Cleared on read.
