Functions B*
(1) Performs the multiplication of BCD data of device specified at (S1) and the BCD
data of device specified at (S2), and stores the result into the device specified at
(D).
(2) At (S1) and (S2), 0 to 9999 (BCD 4 digits) can be specified.
B/
(1) Performs devision of the BCD data specified at (S1) and the BCD data specified
at (S2), and stores the division result into the device specified at (D).
(2) In regards to the operation result, the quotient and remainder are stored by use
of 32 bits.
Quotient (BCD 4 digits): Stored to the lower 16 bits.
Remainder (BCD 4 digits): Stored to the upper 16 bits.
(3) (D) will not store the remainder of the dividion result if it is a bit device.
