Outline
This instruction outputs ASCII code data to outputs (Y) in parallel.

2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (PR)
ASCII codes stored of to +3 are output to to +7 in turn by one character at a time in the
time division method.
Eight bytes are sent from the low-order 8 bits (1 byte) of first to the high-order 8 bits (1 byte) of +3 at the end.
When data is stored from to +3 as shown in the table below, data is sent in the order of A to H of "2.
Timing chart".
2. Timing chart
Types of output signals
• to +7: Sending output ( handles low-order bits, and +7 handles high-order bits.)
• +8: Strobe signal
• +9: Execution flag which operates as shown in the above timing chart
