Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Relay FIFO Size
H'0: Port 0 to 1: 3 Kbytes
H'1: Port 0 to 1: 4 Kbytes
H'2: Port 0 to 1: 5 Kbytes
H'3: Port 0 to 1: 6 Kbytes
H'4: Port 0 to 1: Not used
H'5: Port 0 to 1: 1 Kbyte
H'6: Port 0 to 1: 2 Kbytes
H'7: Setting prohibited
This register must not be written to once after relay
operations have been enabled (after the FWEN0 bit in
TSU_FWEN0 or the FWEN1 bit in TSU_FWEN1 is set
to 1).
When data equal to or greater than the specified size of
64 bytes is stored in the relay FIFO, an overflow is
detected and the frame being transferred is discarded.
