Description amended

Bit 27—Receive Frame Error (RFE): Indicates that one or other bit of

the receive frame status indicated by bits 26 to 0 is set. Whether or

not the multicast address frame receive information which is part of

the frame status, is copied into this bit is specified by the

transmit/receive status copy enable register.

• Bits 26 to 0—Receive Frame Status 26 to 0 (RFS26 to RFS0):

These bits indicate the error status during frame reception.

• RFS26 to RFS10—Reserved

• RFS9—Receive FIFO Overflow (corresponds to RFOF bit in

EESR)

• RFS8—Reserve Abort Detect

Note:

This bit is set to 1 when any of Receive Frame Status

bit 9, bit 7, bits 4 to 0 is set. When this bit is set, the

Receive Frame Error bit (bit 27: RFE) is set to 1.

• RFS7— Receive Multicast Address Frame (corresponds to

RMAF bit in EESR)

• RFS6—Reserved*

• RSF5— Receive Frame Discard Request Assertion

(corresponds to RFAR bit in EESR)*

• RFS4—Receive Residual-Bit Frame (corresponds to RRF bit in

EESR)

• RFS3—Receive Too-Long Frame (corresponds to RTLF bit in

EESR)

• RFS2—Receive Too-Short Frame (corresponds to RTSF bit in

EESR)

• RFS1—PHY-LSI Receive Error (corresponds to PRE bit in

EESR)

• RFS0—CRC Error on Received Frame (corresponds to CERF bit

in EESR)

Note: 1. Only HD6417616 is effective. HD6417615 is Reserved

bit.
