15.8 FNC 77 – PR / Print (ASCII Code)
Outline
This instruction outputs ASCII code data to outputs (Y) in parallel.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (PR)
ASCII codes stored in low-order 8 bits (1 byte) of to +7 are output to to +7 in turn by one
character at a time in the time division method.
The timing chart below shows a case in which the following ASCII codes are stored in to +7.
Eight bytes are sent from = "A" at first to " +7 = "H" at the end.
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
Operand Type Description Data Type
