Processing details
• These instructions convert the (n) characters (digits) within the hexadecimal code data specified by (s) to ASCII, and store
the converted data in the device specified by (d) and later.
• The 16-bit mode and 8-bit mode options are available for the ASCI(P) instructions. For the operation in each mode, refer to
the proceeding pages.
• 16-bit conversion mode (while SM8161 is OFF)
Each digit of hexadecimal data stored in the device specified by (s) and later is converted into ASCII code, and transferred to the upper 8 bits and lower 8
bits of each device specified by (d) and later. SM8161 must always be off in the 16-bit conversion mode.
In the following program, conversion is executed as follows:
Devices specified by (s) and later

(D101)=1234H
(D102)=5678H
