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 the "m1"th digit are transferred to the transfer destination
starting
from the "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 the "m1"th digit are
transferred to
’ starting from the "n"th
digit.
The digits of 10
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.
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.
