(2) Operation procedure
Caution
Remark
Even after communication is stopped, the pin level is retained. To resume the operation, re-set the
SOm register (see Figure 13-35 Procedure for Resuming Master Reception).
After setting the PER0 register to 1, be sure to set the SPSm register after 4 or more clocks
have elapsed.

CHAPTER 13 SERIAL ARRAY UNIT
User’s Manual U18432EJ5V0UD
Enable clock output of the target channel
by setting a port register and a port mode
register.
Set the operation clock.
Set an operation mode, etc.
Set a communication format.
Set a transfer baud rate.
Manipulate the CKOmn bit and set an
initial output level.
SEmn = 1 when the SSmn bit of the
target channel is set to 1.
Set dummy data to the SIOp register (bits
7 to 0 of the SDRmn register) and start
communication.
Release the serial array unit from the
reset status and start clock supply.
Write 1 to the STmn bit of the target
channel.
Stop communication in midway.
