Processing details

• These instructions combine the (n) bytes of lower 8 bits of 16-bit binary data in the device specified by (s) and later in units

of words, and store the combined data in the device specified by (d) and later.

• The (n) bytes of upper 8 bits of 16-bit binary data in the device specified by (s) and later are ignored. When (n) is an odd

number, the upper 8 bits of the device where 'n'th-byte data is stored are filled with 0s.

: th byte data

(1) The upper byte data are ignored.

*1 Values after the decimal point are rounded up.

When (n) is 5, the lower 8 bits of the data in the device specified by (s) to (s)+4 are combined and stored in the device

specified by (d) to (d)+2.

(2) Filled with 00H.

• Setting the number of bytes for (n) automatically determines the range of byte data in the device specified by (s) and the

range of the device specified by (d) for storing the combined data.

• If (n) is 0, no processing is performed.

• The upper 8 bits in the device specified by (s) and later are ignored, and only the lower 8 bits are processed.

• Even when the ranges of the device where the combination target data is stored and the device for storing the combined

data overlap, the processing is performed normally.

Range of the device where the combination target data is

(s)+0 to (s)+(n)-1

When the lower 8 bits of D11 to D16 are stored in D12 to D14

Operation error

There is no operation error.
