Description
Decodes the contents of 16-bit data specified by S according to the contents of n. The decoded result is
stored in the area starting from 16-bit area specified by D.
The length of the area required to store decoding results changes depending on the length of the data being
decoded.
How to specify control data “n”
n specifies the starting bit position and the number of bits to be decoded using hexadecimal data.
Number of bits to be decoded
(set range: H0 to H8)
Starting bit position to be decoded
