CHAPTER 11 SERIAL ARRAY UNIT

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.

Set the initial output level of the serial

data (SOmn).

Set the SOEmn 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 SSmn bit of the target channel to 1

(SEmn bit = 1: to enable operation).

Initial setting is completed.

Set transmit data to the SIOp register

(bits 7 to 0 of the SDRmn register) and

wait for a clock from the master.
