Description
Sets the priority control mode of MAC-1 transmission
and port 0 to 1 relay operations.
H′0: Round robin
H′1: Transmission priority
H′2: Relay priority
H′4: Round robin, however switched to relay priority
H′5: Transmission priority, however switched to relay
Others: Setting prohibited
Reserved
These bits are always read as 0. The write value
should always be 0.
Sets the threshold value of the port 0 to 1 TSU FIFO
capacity in 64-byte units in the event switching to
relay priority when PRIMD12 to PRIMD10 are set to
H′4 or H′5.
H′00: 0 byte
H′01: 64 bytes
H′02: 128 bytes
H′5E: 6016 bytes
H′5F: 6080 bytes
Settings are disabled for H′60 to H′FF.
When set to H′00, relay always takes priority. When
the value set is above the port 0 to 1 TSU FIFO
capacity set by the FCM2 to FCM0 in TSU_FCM, if
the PRIMD12 to PRIMD10 are H′4, round robin will
always be set. If the PRIMD12 to PRIMD10 are H′5,
transmission always takes priority.
