CHAPTER 11 SERIAL ARRAY UNIT
User’s Manual U17854EJ9V0UD
Release the serial array unit from the
reset status and start clock supply.
Set the operation clock.
Set an operation mode, etc.
Set a communication format.
Set bits 15 to 9 to 0000000B for baud
rate setting.
Enable data input and clock input of the
target channel by setting a port register
and a port mode register.
SE0n = 1 when the SS0n bit of the target
channel is set to 1.
Wait for a clock from the master.
Write 1 to the ST0n bit of the target
channel.
Stop communication in midway.
