FNC 82 – ASCI / Hexadecimal to ASCII Conversion
Outline
This instruction converts hexadecimal codes into ASCII codes.
On the other hand, BINDA (FNC261) instruction converts binary data into ASCII codes, and ESTR (FNC116)
instruction converts binary floating point data into ASCII codes.
→
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)
Among hexadecimal codes stored in
and later, "n" characters (digits) are converted into ASCII codes,
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 following pages.
