Description
*BL(425) multiplies BCD values in Md and Md+1 and Mr and Mr+1 and out-
puts the result to R, R+1, R+2, and R+3.
Flags
Precautions
If Md, Md+1 and/or Mr, Mr+1 are not BCD, an error will be generated and the
Error Flag will turn ON.
If as a result of the multiplication, the content of R, R+1, R+2, R+3 is
00000000 hex, the Equals Flag will turn ON.
Examples
When CIO 000000 is ON in the following example, D00101, D00100, D00111,
and D00110 will be multiplied as 8-digit unsigned BCD values and the result
will be output to D00123, D00122, D00121 and D00120.
