6 BASIC INSTRUCTIONS
6.5 Data Conversion Instructions
Precautions
• Make sure that only ASCII codes "0" to "9" and "A" to "F" are stored in the device specified by (s).
• If ASCII data is not stored in the device specified for (s) by the HEXA(P) instructions, an operation error occurs and
conversion into hexadecimal code is disabled. Especially, note that when SM8161 is OFF (16-bit conversion mode), ASCII
code should be stored in high-order 8 bits of the device specified by (s).
• The number of points occupied by the device specified by (d) varies depending on the ON/OFF status of SM8161. When
SM8161 is on (8-bit conversion mode), as many points as the number of characters are occupied, and when SM8161 is
OFF (16-bit conversion mode) as many points as the (number of characters 2) are occupied.
• The SM8161 flag is also used for the RS2, ASCI(P), CCD(P) and CRC(P) instructions. When using these instructions and
the HEXA(P) instructions in the same program, make sure to set SM8161 to ON or OFF just before each instruction so that
SM3161 does not affect another instruction.
Operation error
Number of specified characters and conversion result "." indicates "0".
Error code
