Function and operation explanation
1. 16-bit operation(BCD, BCDP)
This instruction converts the binary (BIN) data specified by into binary-coded decimal (BCD) data, and
transfers the converted BCD data to the device specified by .
• The data of the device specified by can be converted if it is within the range from K0 to K9999 (BCD).
• The table below shows digit specification for the devices specified by and respectively.
2. 32-bit operation(DBCD, DBCDP)
This instruction converts the binary (BIN) data specified by into binary-coded decimal (BCD) data, and
transfers the converted BCD data to the device specified by .
• The data of the device specified by can be converted if it is within the range from K0 to K99999999
(BCD).
• The table below shows digit specification for the devices specified by and respectively.
