9.2.2
This register specifies the maximum frame length (in bytes) that can be received by the SH7615
Bits 31 to 12—Reserved: These bits are always read as 0. The write value should always be 0.
Bits 11 to 0—Receive Frame Length (RFL)
H'000–H'5EE
H'5EF
H'5F0
H'7FF
H'800–H'FFF
Notes: 1. The frame length refers to all fields from the destination address up to and including the
