CHAPTER 11 SERIAL ARRAY UNIT
User’s Manual U17854EJ9V0UD
Release the serial array unit from the
reset status and start clock supply.
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 a transfer baud rate.
Set an output data level.
Manipulate the SOmn bit and set an
initial output level.
Set the SOEmn bit to 1 and enable data
output of the target channel.
SEmn = 1 when the SSmn bit of the
target channel is set to 1.
Set transmit data to the TXDq register (bits
7 to 0 of the SDRmn register) and start
communication.
