6 BASIC INSTRUCTIONS
6.6 Data Transfer Instructions
Digit move
SMOV(P)
These instructions distribute and compose data in units of nibble (4 bits).
■Descriptions, ranges, and data types
*1 Set so that m2m1, m2n.
■Applicable devices
These instructions distribute and compose data in units of nibble (4 bits). The contents of the transfer source (s) and transfer
destination (d) are converted into 4-digit BCD (0000 to 9999). (m2) nibbles starting from the (m1)th nibble are transferred to
the transfer destination (d) starting from the (n)th nibble, converted into binary, and then stored to the transfer destination (d).
■Extension function
When SM8168 is set to ON first and then SMOV instruction is executed, conversion from binary to BCD is not executed. Data
is moved in units of 4 bits.

• While the command input is OFF, the transfer destination (d) does not change.
• When the command input turns ON, only the specified digits in the transfer destination (d) are changed. The transfer source (s) and unspecified digits in the
transfer destination (d) do not change.
(1): (s) is converted from binary to BCD data.
(2): (m2) digits starting from the (m1)th digit are transferred (combined) to
(d)' starting from the (n)th digit. The first and fourth digits of (d)' are not
affected even if data is transferred from (s)'.
(3): The combined data (BCD) is converted into binary, and stored to (d).
