6.2.7 4-digit BCD data multiplication and division
B*, B/
B/(P)
(1) Divides BCD data specified for
by BCD data specified for
, and stores the result to the
variable specified for
.
(2) Quotient and remainder of the division result are stored in 32-bit data.
Quotient (4-digit BCD):
Stored to
[0] (16 bits).
Remainder (4-digit BCD):
Stored to
[1] (16 bits).

In any of the following cases, an operation error occurs, the error flag (SM0) is turned ON, and
the corresponding error code is stored to SD0.
• The
or
BCD value is outside the range of 0 to 9999.
(Error code: 4100)
• Attempt to divide
by 0.
(Error code: 4100)
