18.3.27 Transmit/Relay Priority Control Mode Register (Port 0) (TSU_PRISL0)
TSU_PRISL0 sets the priority control mode when the transmission request from the E-DMAC to
MAC-0 come into collision with port 1 to 0 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).
