16.3 FNC 82 – ASCI / Hexadecimal to ASCII Conversion
16.3 FNC 82 – ASCI / Hexadecimal to ASCII Conversion
Outline
This instruction converts hexadecimal code into ASCII code.
On the other hand, BINDA (FNC261) instruction converts binary data into ASCII code, and ESTR (FNC116) instruction
converts binary floating point data into ASCII code.
→ For BINDA (FNC261) instruction, refer to Section 29.6.
→ For ESTR (FNC116) instruction, refer to Section 18.4.

Explanation of function and operation
1. 16-bit operation (ASCI and ASCIP)
"n" hexadecimal code characters (digits) stored in and later are converted into ASCII code, and then stored to
the devices and later.
The 16-bit mode and 8-bit mode options are available for this instruction. For operation in each mode, refer to the
proceeding pages.
