*1: Output data is hexadecimal.
*2: By executing the STC (40) instruction instead of the CLC (41) instruction, turning the carry
(25504) ON, and executing the SLC3 instruction, the input value of the SLC3 instruction for
DM 0000 will be treated as a negative value.
* "n" indicates the allocated word for analog output 1.
