Description
Reception Enable
This bit setting becomes valid at the start of the next
frame (at the rising edge of the SIOFSYNC signal). When
the 1 setting for this bit becomes valid, the SIOF begins
the reception of data from the RXD_SIO pin. When
receive data is stored in 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.
0: Disables data reception from RXD_SIO
1: Enables data reception from RXD_SIO
Reserved
These bits are always read as 0. The write value should
always be 0.
Transmission Reset
This bit setting becomes valid immediately. When the 1
setting for this bit becomes valid, the SIOF immediately
sets transmit data from the TXD_SIO pin to 1, and
initializes the transmission data register and transmission-
related status register. The following are initialized.

As the SIOF is cleared automatically at the completion of
reset operation, this bit is always read as 0.
0: Transmission operation is not reset
1: Resets transmission operation
