Output
Function
When the input is ON, this instruction converts the lower 4 bits data of A into the 7 segment code,
and stores it in B. The 7 segment code is normally used for a numeric display LED.

Example
When X000 is ON, the lower 4 bits data of RW15 is converted into the 7 segment code, and
the result is stored in lower 8 bits of RW10. 0 is stored in upper 8 bits of RW10.
For example, if RW15 is H0009, the corresponding 7 segment code H006F is stored in RW10.
F E D C B A 9 8 7 6 5 4 3 2 1 0
RW15 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 (H0009)
Upper 12 bits are ignored
RW10 0 0 0 0 0 0 0 0 0 1 1 0 1 1 1 1 (H006F)
0 is stored in upper 8 bits
