1. Set the clock selection in SCSCR2.
2. Set the data transfer format in SCSMR2.
3. Write a value corresponding to the SCBRR2.
4. Wait at least one bit interval, then set the

When clock output is selected, it is output
immediately after SCSCR2 settings are made.
(Not necessary if an external clock is used.)
TE bit or RE bit in SCSR2 to 1. Also set the
RIE and TIE bits.
Setting the TE and RE bits enables the
TxD2 and RxD2 pins to be used. When
transmitting, the SCIF will go to the mark
state; when receiving, it will go to the idle
state, waiting for a start bit.
