Section 18 Ethernet Controller (EtherC)
18.3.28 Transmit/Relay Priority Control Mode Register (Port 1) (TSU_PRISL1)
TSU_PRISL1 sets the priority control mode when the transmission request from the E-DMAC to
MAC-1 come into collision with port 0 to 1 relay operations. Writing to this register is prohibited,
after relay operations have been enabled once (after the FWEN0 in TSU_FWEN0 or the FWEN1
in TSU_FWEN1 is set to 1).

Description
Sets the threshold of the port 1 to 0 TSU FIFO
capacity in 64-byte units in the event switching to
relay priority when PRIMD02 to PRIMD00 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 1 to 0 TSU FIFO
capacity set by the FCM2 to FCM0 in TSU_FCM, if
the PRIMD02 to PRIMD00 are H′4, round robin will
always be set. If the PRIMD02 to PRIMD00 are H′5,
transmission always takes priority.
Description
Reserved
These bits are always read as 0. The write value
should always be 0.
