Processing details
• When SM773 is OFF, the contents of (s) and (d) are converted to 4-digit BCD (0000 to 9999). After the data in lower (n2)
digits from the (n1)th digit is transferred (combined) to (d) starting from the (n3)th digit, the data is converted into BIN and
then stored in (d).
• When SM773 is on, conversion from BIN to BCD is not performed and data are shifted in units of 4 bits.
• When digit specification of bit is used for (n1), the number of digits becomes the specified number of digits  4 bits from the
start bit device.
Ex.
To specify "3 digits  4 bits" from X0:
(1) Specified constant
(2) Start bit device
Digit specification denotes the "specified number of digits 34 bits" = 12 bits from the start bit device X0.

In the case of (n1) = 4, (n2 )= 2 and (n3) = 3
1. Conversion
(s) is converted from binary to BCD data.
2. Shifting
Lower (n2) digits starting from the (n1)th digit are
transferred (combined) to (d)' starting from the (n3)th digit.
In the case of this example, the first and fourth digits of (d)'
are not affected even if data is transferred from (s)'.
3. Conversion
The combined data (BCD) is converted into binary, and
stored to (d).
In the case of (n1) = 4, (n2 )= 2 and (n3) = 3
1. Shifting data in units of 4 bits
Lower (n2)4-bit data from (n1)4th bit is transferred
(combined) by lower (n2)4-bit data from (n3)4th bit of
(d). In the case of this example, the first and fourth digits of
(d) are not affected even if data is transferred from (s).
