Function
Receive end of ring
When set, indicates that this is the last descriptor in the receive descriptor ring.
Core10100 returns to the first descriptor in the ring, as specified by CSR3 (start of
receive list address).
Second address chained
When set, indicates that the second buffer's address points to the next descriptor and
not to the data buffer.
Note that RER takes precedence over RCH.
Buffer 2 size
Indicates the size, in bytes, of memory space used by the second data buffer. This
number must be a multiple of four. If it is 0, Core10100 ignores the second data buffer
and fetches the next data descriptor.
This number is valid only when RDES1.24 (second address chained) is cleared.
Buffer 1 size
Indicates the size, in bytes, of memory space used by the first data buffer. This number
must be a multiple of four. If it is 0, Core10100 ignores the first data buffer and uses the
second data buffer.

Function
Receive buffer 1 address
Indicates the length, in bytes, of memory allocated for the first receive buffer. This
number must be longword-aligned (RDES2.(1..0) = '00').

Function
Receive buffer 2 address
Indicates the length, in bytes, of memory allocated for the second receive buffer. This
number must be longword-aligned (RDES3.(1..0) = '00').
