6 BASIC INSTRUCTIONS
6.5 Data Conversion Instructions
Converting ASCII to HEX
HEXA(P)
These instructions convert the ASCII data stored in the number of characters specified by (n) in the device numbers specified
by (s) and later to HEX code data, and store the converted data in the device numbers specified by (d) and later.

Processing details
• These instructions convert the ASCII data stored in the number of characters specified by (n) in the device numbers
specified by (s) and later to HEX code data, and store the converted data in the device numbers specified by (d) and later.
16-bit conversion mode and 8-bit conversion mode options are available for these instructions. For operation in each mode,
refer to the succeeding pages.

• 16-bit conversion mode (while SM8161 is OFF)
The ASCII data stored in high-order 8 bits and low-order 8 bits (byte) of the device specified by (s) is converted to hexadecimal code, and transferred to
the device specified by (d) in units of 4 digits. The number of characters to be converted is specified by (n).
SM8161 is also used for the RS2, ASCI(P), CCD(P), and CRC(P) instructions. When using the 16-bit conversion mode, set SM8161 to normally OFF.
SM8161 is cleared when the CPU module mode is changed from RUN to STOP.
Moreover, when using the 16-bit conversion mode, the ASCII data must also be stored in high-order 8 bits of the device specified by (s).
In the following program, conversion is executed as follows:
