Segment (SEG)
The BCD / Segment instruction converts a four digit HEX value in
the accumulator to seven segment display format. The result resides
in the accumulator.
In the following example, when X1 is on, the value in V1400 is loaded into the lower 16 bits
of the accumulator using the Load instruction. The HEX value in the accumulator is converted
to seven segment format using the Segment instruction. The bit pattern in the accumulator is
copied to Y20–Y57 using the Out Formatted instruction.
