Description
Reserved
These bits are always read as 0. The write value should
always be 0.
TSU Counter Reset
When 1 is written to this bit, the values of registers
TXNCR0/1, TXALCR0/1, RXNLCR0/1, RXALCR0/1,
FWNLCR0/1, and FWALCR0/1 are cleared to 0. Writing
0 does not affect this bit. These bits are always read as
0.
Reserved
These bits are always read as 0. The write value should
always be 0.
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 the FCM2 to FCM0 in the TSU 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.
