Transmit register empty
flag
0 : Data present in transmit
register (during transmission)
1 : No data present in transmit
register (transmission
completed)
0 : Data present in transmit register
(during transmission)
1 : No data present in transmit
register (transmission completed)

Nothing is assigned.
In an attempt to write to this bit, write “0.” The value, if read, turns out to be “0.”
CKPOL CLK polarity select bit
0 : Transmit data is output at
falling edge of transfer clock
and receive data is input at
rising edge
1 : Transmit data is output at
rising edge of transfer clock
and receive data is input at
falling edge
Must always be set to “0”
UFORM ^{Transfer format select bit 0 : LSB first}
(Note 3)
1 : MSB first
0 : LSB first
1 : MSB first
Note 1: Only clock synchronous serial I/O mode and 8-bit UART mode are valid.
