Starting communication
Disable data output of the target channel
by setting a port register and a port mode
register.
Re-set the register to change the
operation clock setting.
Re-set the register to change the
transfer baud rate setting (setting the
transfer clock by dividing the operation
clock (f
MCK )).
Re-set the register to change serial
mode register mn (SMRmn) setting.
Set the initial output level of the serial
data (SOmn).
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 and set
the SEmn bit to 1 (to enable operation).
Set transmit data to the SD
R
mn register
and start communication.
