Reserved
These bits are always read as 0. The write value should
always be 0.
Transmit Reset
0: Does not reset transmit operation
1: Resets transmit operation

This bit setting becomes valid at the start of the next
frame (at the rising edge of the SIOF_SYNC signal).
When the 1 setting for this bit becomes valid, the
SIOF begins the reception of data from the
SIOF_RXD pin. When receive data is stored in the
receive FIFO, the SIOF issues a reception transfer
request according to the setting of the RFWM bit in
SIFCTR.
This bit is initialized by a receive reset.
This bit setting becomes valid immediately. For
details on initialization, see section 22.4.7 (5),
Transmit/Receive Reset.
This bit is automatically cleared by SIOF after
completes a reset, to be always read as 0.
