BITS DESCRIPTIONS
[4] RXGD
The Receive Good Interrupt high indicates the frame reception
has completed.
If the RXGD is high and EnRXGD of MIEN register is enabled, the
RxINTR will be high. Write 1 to this bit clears the RXGD status.
1’b0: The frame reception has not complete yet.
1’b1: The frame reception has completed.
[3] PTLE
The Packet Too Long Interrupt high indicates the length of the
incoming packet is greater than 1518 bytes and the incoming
packet is dropped. If the ALP of MCMDR register is set, the long
packet will be regarded as a good packet and PTLE will not be
set.
If the PTLE is high and EnPTLE of MIEN register is enabled, the
RxINTR will be high. Write 1 to this bit clears the PTLE status.
1’b0: The incoming frame is not a long frame or S/W wants to
receive a long frame.
1’b1: The incoming frame is a long frame and dropped.
[2] RXOV
The Receive FIFO Overflow Interrupt high indicates the RxFIFO
overflow occurred during packet reception. While the RxFIFO
overflow occurred, the EMC drops the current receiving packer. If
the RxFIFO overflow occurred often, it is recommended that
modify RxFIFO threshold control, the RxTHD of FFTCR register,
to higher level.
If the RXOV is high and EnRXOV of MIEN register is enabled, the
RxINTR will be high. Write 1 to this bit clears the RXOV status.
1’b0: No RxFIFO overflow occurred during packet reception.
1’b0: RxFIFO overflow occurred during packet reception.
[1] CRCE
The CRC Error Interrupt high indicates the incoming packet
incurred the CRC error and the packet is dropped. If the AEP of
MCMDR register is set, the CRC error packet will be regarded as
a good packet and CRCE will not be set.
If the CRCE is high and EnCRCE of MIEN register is enabled, the
RxINTR will be high. Write 1 to this bit clears the CRCE status.
1’b0: The frame doesn’t incur CRC error.
1’b1: The frame incurred CRC error.
