(c) Control conditions
• Designation of the conversion data address (APSHXXXX)
Designate the address where the data to be converted are stored.
If “BYT = 1”, continuous two bytes are used.
• Designation of the converted data address
Designate the address where the result of conversion is stored.
If “BYT = 1”, continuous two bytes are used.
• Designation of the number of bytes (BYT)
BYT = 0: The data to be processed are 1-byte data.
BYT = 1: The data to be processed are 2-byte data.
• Designation of the conversion type (CNV)
CNV = 0: Conversion of binary data to BCD data.
CNV = 1: Conversion of BCD data to binary data.
• Reset (RST)
RST = 0: Error output R1 is not reset.
RST = 1: Error output R1 is reset.
• Execution command (ACT)
ACT = 0: The DCNV instruction is not executed.
ACT = 1: The DCNV instruction is executed.
• Error output (R1)
R1 = 0: Normal
R1 = 1: Error
(An attempt is made to convert the binary data when “CNV = 1”, or the byte
length is exceeded when “CNV = 0”.)
