Starting target for communication
Stop the target for communication or wait
until the target completes its operation.
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 division
ratio of the operation clock 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.
Cleared by using SIRmn register if FEF,
PEF, or OVF flag remains set.
Set the SOEm register and stop the
output of the target channel.
Manipulate the SOmn bit and set an
initial output level.
Set the SOEm register and enable the
output of the target channel.
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.
Set transmit data to the SIOp register
(bits 7 to 0 of the SDRmn register) and
wait for a clock from the master.
Start the target for communication.
