Description
These bits set the threshold of the port 0-to-1 relay
FIFO size in 64-byte units in the event of switching to
relay priority when bits PRIMD1[2:0] are set to H'4 or
H'5.
H'00: 0 byte
H'01: 64 bytes
H'02: 128 bytes
H'5E: 6,016 bytes
H'5F: 6,080 bytes
Settings are disabled for H'60 to H'FF.
When H'00 is set in these bits, relay always takes
priority. When the value set is equal to or above the
port 0-to-1 relay FIFO size set by bits FCM[2:0] in
TSU_FCM, if bits PRIMD1[2:0] are H'4, round robin will
always be set. If bits PRIMD1[2:0] are H'5, transmission
always takes priority.
