FUN 185
7SEG
7 segment decode
Expression
Input − [ A 7SEG B ]− 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.
RW15
F E D C B A 9 8 7 6 5 4 3 2 1 0
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 1 | (H0009) | |
| Upper 12 bits are ignored |
