Outline of operation
● This instruction encodes a part of a device address value or a constant specified by [S], and
stores the result to the device address specified by [D].
● The target section to be encoded is specified by the control data [n].
● If multiple bits are ON in the target section for encoding, the higher bit is enabled.
● Encode the content for 2nL bits, starting with the device address specified by [S]. The
encoded result is stored as a decimal number within 8 bits from the bit specified by "nH".
● In the device address specified by [D], portions other than the one storing the conversion
result should be 0 (should be set to 0).
