REJ09B0292-0200
Bit 30—Receive Descriptor List Last (RDLE): Indicates that this descriptor is the last in the
receive descriptor list. After completion of the corresponding buffer transfer, the E-DMAC
references the first receive descriptor. This specification is used to set a ring configuration for the
receive descriptors.
Bit 30: RDLE
Description
0
This is not the last receive descriptor list
1
This is the last receive descriptor list (the next descriptor is inactive)
Bits 29 and 28—Receive Frame Position 1, 0 (RFP1, RFP0): These two bits specify the
relationship between the receive buffer and receive frame.
Bit 29:
RFP
Bit 28:
RFP
Description
0
0
Frame reception for receive buffer indicated by this descriptor continues
(frame is not concluded)
1
Receive buffer indicated by this descriptor contains end of frame (frame is
concluded)
1
0
Receive buffer indicated by this descriptor is start of frame (frame is not
concluded)
1
Contents of receive buffer indicated by this descriptor are equivalent to one
frame (one frame/one buffer)
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.
Bit 27: RFE
Description
0
No error during reception
(Initial value)
1
An error of some kind occurred during reception (see bits 26 to 0)
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
