SMOV: Shifted transfer
◆
Overview
The SMOV instruction transfers m2 bits starting from the m1th bit in S to m2 bits starting from the nth bit in D.

Function
The SMOV instruction requires contact driving and has a maximum of ve operands, which are described
as follows:
S is the data source from which bits will be transferred. When M8168 = OFF, the BCD mode (decimal bits)
is enabled. The M operand is in the range 0000 to 9999 and cannot be a negative number. When M8168 =
ON, the BIN mode is enabled. The S operand can be a negative number.
m1 is the number of the initial bit to be transferred. The value range is 1 to 4.
m2 is the number of bits to be transferred. The value range is 1 to m1.
D is the destination variable to which bits are transferred.
n is the initial bit of the destination variable that stores a transferred bit. The value range is m2 to 4.
The data bit transfer process is related to the status of the special ag M8168. When M8168 = OFF, the
BCD mode (decimal bits) is enabled When M8168 = ON, the BIN mode is enabled, whereby every four bits
(hexadecimal) are transferred at a time as a whole unit.
