Description
Port 0 to 1 Relay Operation Enable
0: Port 0 to 1 relay is disabled
1: Port 0 to 1 relay is enabled
When the value of bits FCM[2:0] in the relay FIFO size
select register (TSU_FCM) is set to H'4, setting this bit
to 1 is prohibited.
Reserved
These bits are always read as 0. The write value should
always be 0.
