CHAPTER 11 SERIAL ARRAY UNIT
User’s Manual U17854EJ9V0UD
Release the serial array unit from the
reset status and start clock supply.
Set the SOE0n bit to 1 and enable data
output of the target channel.
Enable data 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 bits 15 to 9 to 0000000B for baud
rate setting.
Manipulate the SO0n bit and set an
initial output level.
SE0n = 1 when the SS0n bit of the target
channel is set to 1.
Set transmit data to the SIOp register
(bits 7 to 0 of the SDR0n register) and
wait for a clock from the master.
