7 APPLICATION INSTRUCTION
7.6 Character string operation instruction
• 8-bit conversion mode (while SM8161 is ON)
Each digit of hexadecimal data stored in the device specified by (s) and later is converted into ASCII code, and transferred to the lower 8 bits of each
device specified by (d) and later. SM8161 must always be on in the 8-bit conversion mode.
In the following program, conversion is executed as follows:
Devices specified by (s) and later
(D100)=0ABCH
(D101)=1234H
(D102)=5678H
ï‚¢Number of specified digits (characters) and conversion result
ï‚¢Bit configuration when (n) is K2
