Processing details
Separates the 16-bit in the device specified by (s) in units of 4 bits, and stores the separated data in
the (n) points of 4 low-order bits in the device starting from the one specified by (d). (n<4)
Processing details
Adds the (n) points of 4 low-order bit data in the device starting from the one specified by (s), and
stores the connected data in the device specified by (d). (n<4)
Processing details
Separates the data in the device, specified by (s1) and later, to the bits in the device specified by
(s2) and later, and stores the separated data in order in the device starting from the one specified
by (d).
Connects the data in the device specified by (s1) and later, in units of bits in the device specified by
(s2) and later, and stores the connected data in order in the device starting from the one specified
by (d).
Processing details
Converts the (n) points of 16 bit data in the device specified by (s) in units of 8 bits, and stores the
converted data in order in the device starting from the one specified by (d).
Connects 8 low-order bits of the (n) points of 16 bit data in the device specified by (s) to 16 bits, and
stores the connected data in order in the device starting from the one specified by (d).
