Operands:
S: English letter to be converted into ASCII code D: Device for storing ASCII code
Explanations:
1. S: enter 8 Engligh letters by using WPLSoft on computer or enter ASCII code by HPP.
2. See the specifications of each model for their range of use.
3. Flag: M1161 (8/16 bit mode switch)
4. If the execution of this instruction is connected to a 7-segment display, the error message can be displayed by
English letters.
Program Example:
1. When X0 = On, convert A ~ H into ASCII code and stored it in D0 ~ D3.

2. When M1161 = On, every ASCII code converted from the letters will occupy the lower 8 bits (b7 ~ b0) of a
register. The upper 8 bits are invalid (filled by 0). One register stores a letter.
