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

receiving function is enabled.

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.
