Ù
(a) Function
The instruction converts the binary data to BCD data and the BCD data to binary data.
(b) Example
(c) Control conditions
• Designation of the conversion data address (APSH#XXXX)
Designate the address where the data to be converted is stored.
Both the binary and BCD data use 4 bytes.
The sign of BCD data is set at the most significant bit position.
Therefor, the expression of a numeric value within the range of ± 9999999 is possible.
• Designation of the converted data address (APSH#XXXX)
Designate the address where the data result of conversion is stored.
Both the binary and BCD data use 4 bytes.
• Designation of the number of bytes (LD#XXXX.X)
LD = 0: No conversion
= 1: 4bytes, = 0: Skip
