Explanation of function and operation
1. 16-bit operation (SMOV and SMOVP)
The contents of the transfer source and transfer destination are converted into 4-digit BCD (0000 to
9999) respectively. "m2" digits starting from "m1"th digit are transferred (composed) to the transfer destination
starting from "n"th digit, converted into binary, and then stored to the transfer destination .
• While the command input is OFF, the transfer destination does not change.
• When the command input turns ON, only the specified digits in the transfer destination are changed. The
transfer source and unspecified digits in the transfer destination do not change.
[1] is converted from binary into BCD.
[2] "m2" digits starting from "m1"th digit are
transferred (composed) to ’ starting
from "n"th digit.
The digits of 10
3
and 10
0
of ’ are not
affected even if data is transferred from
’.
[3] The composed data (BCD) is converted into
binary, and stored to .
2. Extension function
When M8168 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.
Program example
The data on three-digit digital switches are composed, and stored as binary data to D2.

1-digit BCD data of D1 is transferred to
the 3rd digit (BCD data) of D2, and
automatically converted into binary data.
