Operands:

S: Device for storing ASCII code (occupies 4 consecutive devices) D: External ASCII code output points (occupies 10 consecutive devices)

Explanations:

1.This instruction will output the ASCII codes in the 4 registers starting from S through output points started from D.

2.D0 ~ D7 map to source data (ASCII code) directly in order, D10 is the scan signal and D11 is the execution flag.

3.This instruction can only be used twice in the program.

4.Flags: M1029 (PR execution completed); M1027 (PR output mode selection).

Program Example 1:

1.Use API 76 ASC to convert A ~ H into ASCII codes and store them in D0 ~ D3. After this, use this instruction to output the codes in sequence.

2.When M1027 = OFF and X20 = ON, the instruction will designate Y20 (lowest bit) ~ Y27 (highest bit) as the output points and Y30 as scan signals, Y31 as execution flag. In this mode, users can execute an output for 8 letters in sequence..

3.If X20 turns from ON → OFF during the execution of the instruction, the data output will be interrupted, and all the output points will be OFF. When X20 = ON again, the data output will

start from the first letter again.
