Be sure to write "000".

RFST
R/W
Bytes used in receive FIFO.
0: Maximum
1: Same as FILL level of receive FIFO
The number of receive FIFO bytes to be used is selected. (Note1)
0: The maximum number of bytes of the FIFO configured (see also <CNFG>).
1: Same as the fill level for receive interrupt generation specified by SC0RFC <RIL[1:0]>.
3
TFIE
R/W
Specify transmit interrupt for transmit FIFO.
0: Disabled
1: Enabled
When transmit FIFO is enabled, transmit interrupts are enabled or disabled by this parameter.
2
RFIE
R/W
Specify receive interrupt for receive FIFO.
0: Disabled
1: Enabled
When receive FIFO is enabled, receive interrupts are enabled or disabled by this parameter.
1
RXTXCNT
R/W
Automatic disable of RXE/TXE.
0: None
1: Auto disable
Controls automatic disabling of transmission and reception.
Setting "1" enables to operate as follows.
Half duplex
Receive
When the receive shift register, receive
b
uffers and receive FIFO are filled up to
the specified number of valid bytes, SCxMOD0<RXE> is automatically set to "0"
to inhibit further reception.
Half duplex
Transmit
When the transmit shift register, transmit buffers and the transmit FIFO are emp-
ty, SCxMOD1<TXE> is automatically set to "0" to inhibit further transmission.
Full duplex
When either of the above two conditions is satisfied, <TXE> and <RXE> are au-
tomatically set to "0" to inhibit further transmission and reception.
0
CNFG
R/W
FIFO enable.
0: Disabled
1: Enabled
Enables FIFO.(Note2)
When <CNFG> is set to "1", FIFO is enabled. If FIFO is enabled, the SCOMOD1 <FDPX[1:0]> setting auto-
matically configures FIFO as follows:
Half duplex
Receive
Receive FIFO 4bytes
Half duplex
Transmit
Transmit FIFO 4bytes
Full duplex
Receive FIFO 2bytes and Transmit FIFO 2bytes
