1. Format and operation, execution form
2. Set data
3. Applicable devices
S: Refer to "Cautions".
Function and operation explanation
1. 16-bit operation (PR)
ASCII code stored in lower 8 bits (1 byte) of to +7 is issued to to +7 sequentially in time
division character by character.
The following timing chart explains the ASCII code stored in the device specified by .
The transmission sequence begins from ="A", and ends with +7="H", and 8 bytes are transmitted in
total.
