(Selective) ^{Changing setting of SMRmn register}
(Selective) ^{Changing setting of SCRmn register}
(Selective) ^{Changing setting of SOLmn register}
(Essential) ^{Changing setting of SOEm register}
Disable data output of the target channel
by setting a port register and a port mode
register.
Change the setting if an incorrect division
ratio of the operation clock is set.
Change the setting if an incorrect
transfer baud rate is set.
Change the setting if the setting of the
SMRmn register is incorrect.
Change the setting if the setting of the
SCRmn register is incorrect.
Change the setting if the setting of the
SOLmn register is incorrect.
Clear the SOEmn bit to 0 and stop
output.

(Essential)
Starting communication
Manipulate the SOmn bit and set an
initial output level.
Set the SOEmn bit to 1 and enable
output.
Enable data output of the target channel
by setting a port register and a port mode
register.
Set the SSmn bit of the target channel to
1 to set SEmn = 1.
Sets transmit data to the TXDq register
(bits 7 to 0 of the SDRmn register) and
start communication.
