that can be received by this LSI. The settings in this register must not be changed while the
receiving function is enabled.

Description
Reserved
These bits are always read as 0. The initial value
should not be changed.
Receive Frame Length 11 to 0
The frame length described here refers to all fields
from the destination address up to and including the
CRC data. Frame contents from the destination
address up to and including the data are actually
transferred to memory. CRC data is not included in
the transfer.
When data that exceeds the specified value is
received, the part of the data that exceeds the
specified value is discarded.
